Maintaining a healthy diet doesn't have to be expensive or difficult. Oftentimes, the last thing I want to do after a long day is spend an hour in the kitchen laboring over a meal, especially if I'm already ravenous to begin with. In order to resist the glowing lights of the drive-thru on my way home, I use a simple formula to make a quick, healthy dinner any night. There are three parts to this meal: a protein/meat, a complex carbohydrate, and a vegetable.
THE PROTEIN: When you're at the grocery store, check out which meat or fish is on sale. My favorites are boneless skinless chicken breasts and the individually-packaged, frozen salmon fillets (each is only 99 cents at my store). Buy a package, use one piece for dinner, and freeze the rest.
THE COMPLEX CARB: Easy. Keep a couple boxes of 100% whole wheat pasta and/or some brown rice around.
THE VEGETABLE: Again, buy your favorite/on sale/in season vegetables from the produce aisle or farmer's market. I also like to keep a bag of frozen spinach on hand as well. That way, if everything else spoils while sitting in the depths of the fridge or languishing on the counter, there is still no excuse for scrapping your healthy ideals.
I also make sure to keep olive oil, garlic, onion, and parmesan cheese at all times.
I haven't gone grocery shopping in ages but was able to scrape a tasty, healthy meal together using half a zucchini, a random squash, tomato, onion, the last of some whole wheat rotini rattling around the bottom of the box, and a frozen salmon fillet.
Put the (thawed) salmon on a lightly greased baking sheet and rub some olive oil on it. Top with chopped onion, tomato, and pepper (or whatever seasoning you like). Bake about 15 min at 425.
Boil a pot of water, then add the pasta. Cook until tender. Serve with a little parmesan cheese on top.
Heat some olive oil and garlic in a frying pan. Chop up the vegetables, then saute them until soft. Season with salt and pepper.
I always find this meal to be quite satisfying. Plus, it's good for using up odds and ends of produce.
