Need some easy, kid-friendly meal ideas

We make “Lazy Lasagna” — Maccaroni with tomato and meat sauce (whatever veggies you generally like in your sauce) mix the sauce and cooked pasta together in a cassarole dish, sprinkle with cheese and put it in the oven until the cheese melts.  (I’m not a great cook, and my dss are just as picky eaters as my dh, so I’ve never really had much opportunity to exeriment and get good at a lot of great dishes.  We eat a lot of tacos, pizza, chicken and grilled cheese sandwiches at our place!.  Meals are a source of frustration for me!)
