I just realized how lazy we are.
We stick to frozen corn dogs, chicken strips, pizza and cereal, soup, salad, sandwiches and spaghetti. Foods that we basically just need to heat up and don't require any real prepping or cooking. After a long day at the park, we are all too tired to do more than throw something in the oven or microwave. We've also done the grocery store rotisserie, then just paired that with some canned veggies or a baked potato, super easy, and any meat that is left over can be eaten cold on sandwiches. The most ambitious we've ever gotten is a poppyseed chicken casserole. Sort of a staple in the south, and it doesn't really require any seasoning as you can leave the poppy seeds off the top. You use ritz crackers which provide the salt.
