How about some summer squash or zucchini? A tiny bit of oil,onions, squash, garlic sauteed in a pan, maybe with some sweet red pepper for bits of color. Season it with "italian spices" unless you have some fresh herbs.
Or add some fresh tomatoes and it makes a good pasta sauce.
Oh and don't forget rule #1, give it a name, people will eat new foods if you give it a definitive name rather than just saying "squaaaash."
