Preheat oven to 400°F; position rack in middle of oven.
In a large bowl, whisk together eggs; set aside.
In a 10-inch ovenproof nonstick skillet, heat oil over medium heat until shimmering. Add onion and cook, stirring, until it begins to soften, 4 minutes. Add broccoli and cook, stirring, until warmed through, 2 minutes more. Season to taste with salt and pepper.
Pour eggs over vegetables, covering them evenly; cook, gently lifting and pushing cooked edges toward center, allowing liquid egg to fill space, about 4 minutes. Sprinkle with cheese and transfer pan to oven. Bake until frittata is golden brown and puffed up, 12-15 minutes (frittata should be just slightly soft in center). Transfer frittata to a cutting board, cut in 6 wedges and serve immediately.
1 Heat oil in a large non-stick skillet over medium-high heat. Add onion and cook, stirring often, until soft and beginning to brown, 2 to 3 minutes. Add mushrooms, bell pepper, oregano and pepper and cook, stirring often, until the vegetables are wilted and soft, about 7 minutes.
2 Reduce heat to low; sprinkle the vegetables with flour and stir to coat. Stir in broth and soy sauce; bring to a simmer. Remove from the heat, lay cheese slices on top of the vegetables, cover and let stand until melted, 1 to 2 minutes.
3 Divide the mixture into 4 portions with a spatula, leaving the melted cheese layer on top. Scoop a portion onto each toasted bun and serve immediately.
1 Bring a large pot of water to a boil. Cook pasta for 4 minutes. Add frozen broccoli and continue cooking, stirring occasionally, until the pasta and broccoli are just tender, 4 to 5 minutes more.
2 Meanwhile, heat 1½ cups milk in another large pot over medium-high heat until just simmering. Whisk the remaining ¼ cup milk, flour, garlic powder, salt and pepper in a small bowl until combined. Add the flour mixture to the simmering milk; return to a simmer and cook, whisking constantly, until the mixture is thickened, 2 to 3 minutes. Remove from the heat and whisk in Cheddar, Parmesan and mustard until the cheese is melted.
3 Drain the pasta and broccoli and add to the cheese sauce. Return to the heat and cook, stirring, over medium-low heat, until heated through, about 1 minute.
2 5-ounce cans chunk light tuna (see Tip), drained
1 medium shallot, minced (2 tablespoons)
2 tablespoons low-fat mayonnaise
1 tablespoon lemon juice
1 tablespoon minced flat-leaf parsley
⅛ teaspoon salt
Dash of hot sauce
Freshly ground pepper, to taste
2 tomatoes, sliced
½ cup shredded sharp Cheddar cheese
4 slices whole-wheat bread, toasted
Combine tuna, shallot, mayonnaise, lemon juice, parsley, salt, hot sauce and pepper in a medium bowl. Spread ¼ cup of the tuna mixture on each slice of toast; top with tomato slices and 2 tablespoons cheese. Place sandwiches on a baking sheet and broil until the cheese is bubbling and golden brown, 3 to 5 minutes.
Whisk vinegar, shallot, mustard, pepper and salt in a small bowl to combine. Whisk in oil until combined. Place salad greens in a large bowl. Add half of the dressing and toss to coat.
Divide the greens among 4 plates. Arrange equal portions of chicken, egg, tomatoes, cucumber, avocado, bacon and blue cheese (if using) on top of the lettuce. Drizzle the salads with the remaining dressing.
Tips: To poach chicken breasts, place boneless, skinless chicken breasts in a medium skillet or saucepan and add lightly salted water to cover; bring to a boil. Cover, reduce heat to low and simmer gently until chicken is cooked through and no longer pink in the middle, 10 to 15 minutes. To shred the chicken, use two forks to pull it apart into long shreds. To hard-boil eggs, place in a single layer in a saucepan; cover with water. Bring to a simmer over medium-high heat. Reduce heat to low and cook at the barest simmer for 10 minutes. Remove from heat, pour out hot water and fill the pan with a mixture of cold water and ice cubes; let stand until the eggs are completely cooled.
Boil the potatoes for 10 mins until tender. Meanwhile, heat the oil in a large saucepan. Season the meatballs, then brown them all over for about 5 mins. Remove from the pan, drain off any excess fat, then add the onion, garlic and rosemary. Fry gently for 5 mins.
Add passata to the pan, bring to a simmer, then add the meatballs. Simmer for 5 mins or until everything is cooked through. Add the potatoes and peas, then simmer for 1 min. Pack into a flask or reheat at work, add Parmesan, if using, and eat with good crusty bread.
