Hi T.,
I call this one "Moroccan Chicken" -
Chicken breast, tomatoes, pitted kalamata olives, cheese, salt and pepper
Place chicken in a baking dish, salt and pepper it (can also add Parm. cheese) then top with slices of tomato and olives, including the juice from the olives. Cover with tin foil and bake at 350 for 25 minutes. The chicken remains very moist and has tons of flavor from the olive juice. I usually serve with steamed broccoli.
Or you could do a steak seasoned with rosemary served with baked asparagus (drizzle some olive oil, salt and pepper, bake at 350 for 10-15 minutes) Or you could do chicken or steak fajitas. All you have to do is slice the steak into strips and cook, then top off with your favorite salads. We get a cooked chicken from the store and shred it so there's even LESS work involved!
I make slightly more involved meals on the weekend and then refrigerate them until we need them during the week. For example, a veggie lasagna or a mexican 7 layer dip,sloppy joes, chicken enchiladas. None of these are hard but require slightly more time than I care to spend after a long day at work!
I do something similar to Barbilee's suggestion. We have an excel spreadhseet of meals that are in categories of prep time -quick, medium and long. Each Sunday before grocery shopping I make up a menu and then a shopping list based on the meals we choose for that week.
