Preheat oven to 400°. Coat a baking sheet and 1 (3-ounce) chicken breast with cooking spray; bake 30 minutes or until done. Chop 1 small potato into 1-inch cubes; toss with 2 cups broccoli spears, 2 teaspoons olive oil, and salt and pepper to taste. Roast 30 minutes. Mix vegetables with 2 tablespoons crumbled feta cheese and 1 tablespoon red wine vinegar; serve with chicken.
Spray baking sheet with non-stick cooking spray. Place chicken breast and vegetables on sheet, and season with salt and pepper. Spray vegetables with non-stick cooking spray, then spoon tomato sauce on top of chicken. Bake at 350 degrees for 20-25 min or until chicken is cooked through. When 5 minutes left, top chicken with cheese and let melt until finished cooking
Before you start the meal plan, make a pot of the Veggie Soup. Make 2 servings of Overnight Oats, so they can soak in the fridge. It’s also super helpful to prep your veggie snacks—make 4 bags filled with baby carrots and sugar snap peas, and 3 bags filled with broccoli and cauliflower, for alternate days. And if you really want to get ahead, you could also grill the chicken breasts and cook the quinoa and brown rice in advance.
