Summer Squash, Tomato, and Onion Medly

1 yellow summer squash about 6" long
1 large can tomatoes (or one quart home canned)
1 small sweet onion sliced 1/4" slices
Veggie oil
Salt and Pepper to taste
1/2 p 1 teaspoon sugar - optional

Wash and slice summer squash into 1/4" pieces. If using a larger squash remove the seeds.  Peel and slice sweet onion.

In a deep skillet, coat bottom lightly with oil.  On medium heat, saute summer squash and onion until both are softened.  Add tomatoes.  Bring to a simmer.  Add salt and pepper.  Taste.  If too bitter add the sugar to taste.

Any summer squash will work - yellow, zucchini, patty pan etc.
