Summer-garden cheese casserole

This is a thrown together kind of recipe that uses things you probably have a ton of if you have a vegetable garden!

4-5 sliced summer squash and/or zucchini
1/2 sliced vidalia onion
olive oil
salt & pepper
1-2 sliced large tomatoes (or 1-2 handfuls of halved cherry tomatoes)
your favorite shredded cheese
fresh basil

Sautee summer squash/zucchini, onion in olive oil until soft
Season to taste with salt & pepper
Place in casserole, cover with sliced tomatoes, sprinkle with cheese (I used sharp cheddar)
Bake at 350 for about 20-25 minutes until bubbly
Top with shredded basil leaves
Serve!

Notes:
Adjust all ingredients to your taste.
It is good room temperature.
I think the next time I make it - I'll roast the tomatoes first - and may also try adding roasted red peppers.
