There are as many recipes for calabacitas as there are cooks. Here's how DH and I like it. We especially enjoy this in August when zucchini and corn are fresh from the garden. It is a versatile dish - the measurements are estimated. Use whatever fresh vegetables you have on hand...red peppers, grated carrots, jalapenos, diced tomato... For example, if I'm making it for my Yankee parents I omit the poblano and cilantro, and add parsley, resulting in a mild but tasty saute of summer vegetables. Have fun experimenting and enjoy!
