When we first got married, I didn't really know how to cook but maybe 7 things. No good! What I started doing was looking through the weekly circular to find what is on sale and then I'd go to allrecipes.com and type in that meat. (Like, what in the world do I do with cube steak, and what is a roast good for besides pot roast with the veggies?). You type in the meat (or whatever) and search by rating. I found some good things that way, and it helped me find new recipes until I could find my way around the kitchen and develop my own things.
Another thing I do is this: I try to rotate meals by saying 1 day of beef (anything from steaks, any number of versions of burgers from Indian spiced burgers with a cilantro yogurt sauce, taco burgers made with taco seasoning and served with guacamole, I have a couple different meatloafs, chili, taco salad, spaghetti & meatballs, or beef steaks with mushroom gravy, etc), 1 day of chicken (chicken tortilla soup, chicken and rice casserole, king ranch casserole, roasted chicken with veg, etc), 1 day of vegetarian (moussaka and dolmathes, eggplant parmesan, vegetarian lasagna, etc), 1 day of pork or sausage (think sausage and peppers over rice with spaghetti sauce, or red beans and rice with sausage, jambalaya, pork chops with sliced mushrooms and cream of mushroom soup, pork chops with saurkraut and potatoes, pork tenderloin, or served with spiced apples, etc), 1 day of fish (love broiled parmesan tilapia, or tilapia cooked in the skillet with a saffron/wine risotto and mango relish, fried catfish, baked or broiled salmon any number of ways, kenyan fish, fish tacos, shrimp creole, crawfish etouffe, baked shrimp risotto, etc).
That's 5 days for a "schedule" and then we should have leftovers 1 or 2 of those days. If not, we'll do something together like make our own pizzas with whatever we want...or I'll do a sandwich night where we can do egg sandwiches, grilled cheese sandwiches for the kids and grown up grilled cheese for us (slice feta, then red onion and a tomato, then cheddar, then grill as normal) or awesome reuben sandwiches with fried potato slices, chicken, cheese, and mushroom melts, if it's a hot night then something filling but not too heavy: cucumber feta sandwiches (toast the bread, little mayo, slice those up and it's fast and light). Serve with some salad or a soup like tomato basil and it's really easy but still a good dinner.
