I have to say I became creative with a hot plate, toaster oven, bbq and microwave. I can make a yummy meatloaf on the grill! OH wait....I forgot my beloved CROCK POT! I can make a pretty good crock pot mac n' cheese, not as good as my oven baked but better then a box.
After being without an oven for so so long I have been in the mood to make casseroles. So here is one of my favorites. It might not look pretty but it tastes great and it's packed with veggies and protein and you can substitute pasta for rice, I used the veggie bow tie pasta.
This is a take on an Amish dish that my Aunt made when I was little.
I start with a large pan and some olive oil. Drizzle your olive oil and add one small chopped onion and about 4-5 celery stalks, chopped. cook until tender and add two shredded zucchini and 2-3 shredded carrots. cook on medium heat for 2-3 minutes. Add 2 chopped cloves of garlic. Add 1 pound of ground beef and cook through. Add 1 egg to the pan and cook into the meat. It gives the mixture a silky texture. Once the mixture is cooked set aside.

As I said, I used veggie bow tie pasta. Now it's time to layer noodles, meat mixture, sauce and again. It's a two layer dish. Then I top with cheddar cheese and thick sliced tomatoes. On top of each tomato I sprinkle about a tablespoon of bread crumbs...a couple slices of sourdough bread toasted and then crumbled into a little butter in frying pan until all the bread is coated. Bake at 350 degrees for about 30 minutes. This dish is a great make ahead and freeze dish and also makes great leftovers. Just remember to not over cook your noodles")
