In addition to meals that you make ahead, try to come up with some easy healthy meals that require very little prep. Here are a few things that I prepare regularly.....
Ocean Beauty salmon patties..... seasoned and herb crusted. Fairly expensive, but VERY healthy and easy! Can cook in the skillet, oven, grill, or toaster oven. Serve as a burger on a whole wheat roll, on top of a green salad, or as a main dish with some roasted broccoli and quinoa!
Hormel all-natural pork tenderloin.... comes in several marinades such as maple bourbon, teriyaki, lemon pepper, parmesean herb. Takes about 45 minutes to cook (on grill or in oven), but requires NO prep. Again, serve with veggies and maybe brown rice. The rice I make also takes 45 minutes to cook, so it is done at the same time as the pork.
"cold plate" night..... everyone gets bits and blobs of different stuff (depending on their likes/dislikes, diet, allergies, etc) like hummus, cheese, veggies (raw or cooked), boiled eggs, pretzels, whole grain crackers, sardines, cold salads like quinoa salad or couscous salad, couscous salad, bean salad, etc., sliced fruit.... great for hot summer nights.
yogurt parfait night..... I was afraid I would have a hard time convincing my family to embrace this for dinner instead of breakfast, but they seemed to really enjoy it! Make a "buffet" with containers of yogurt (plain, vanilla, greek, soy.... whatever type your family likes), granola or other "crunchies" (I like FiberOne cereal), and fruit.... blueberries, diced strawberries, mango, peaches, cherries, pineapple.... whatever!
And remember, the crockpot is your friend! I make a very easy "chicken cacciatore" in my crockpot.... skinless chicken thighs or leg quarters work well for this (I dislike breast)... put meat in the crockpot, dump on some sliced onions, peppers, mushrooms (if you are really pressed for time you could cut these the night before or even bought them pre-sliced at the salad bar).... cover with your spaghetti sauce of choice, cook all day on low (8 hours) and serve over or next to plain pasta!
I'll give this some more thought and try to come up with some more ideas for you...........................P
