This time of year you may have lots of squash from the garden or farmer's market so I will share out absolute favorite way to cook up a batch of squash into cheesy summer squash.
Take any summer squash and dice into junks. This is a good time to clean out your crisper drawer of any thing good to saute. I use mushrooms, tomatoes, onions, bell peppers. Saute all veggies until tender to your liking in olive oil and a little bit of butter. Season with pepper and salt. Just as the sauted vegetables are near done, sprinkle some grated cheddar cheese on top and turn off flame. Let vegetables sit without stirring until cheese is melted. Serve immediately.
