Summer Vegetable Bounty

What to do with all the zucchini, yellow summer squash, tomatoes, etc at the farmers market?  My mom has a tasty and nutritious super easy combination:: simply chop your vegetables into similarly-sized pieces, and then place in a microwave-safe dish.  Pop it in the microwave for 8 to 10 minutes.  It will steam in its own juices and get nice and yummy!  Top with grated cheese of your choice, if you like.  It works very well as a side dish to a grilled item.
