Ah, the dinner rut. It's so hard to get out of it! We like green salads with penne pasta in it along with some grilled or baked chicken tossed in (with tomato, carrots, cucumbers). You can add parmesan and red onions also if you like. Everyone in our house devours it. Taco salads are good also. You can let each person put their own together (chips, meat, cheese, tomatoes, cukes, corn, sour cream, guacamole, salsa (my youngers like ketchup instead), black beans, whatever you like). If you let your daughter choose what she puts on it from what you have prepared, she's more likely to eat it. Also, we marinade chicken with teryaki sauce and grill it. Then, serve with garlic/butter noodles and green beans. Big hit. We make our home version of Chipolte, which is so yummy. I just googled recipes for that and got a good one. Roasts are very easy and good. I use the Pioneer Woman's recipe with GREAT success. It turns out perfect every time, which is a huge bonus. http://thepioneerwoman.com/cooking/2010/02/perfect-pot-ro...
Actually, while you are there, look up other recipes. I make a lot of hers, and we've never been disappointed. They are not difficult, don't require lots of weird ingredients, and always satisfy the family. Enjoy!
