My honey LOVED this. He said he's looking forward to leftovers tomorrow. He was quite surprised when I told him it had zucchini, and he didn't even notice the corn. I reduced the corn by half (because he doesn't like corn), and used more zucchine. I didn't have black beans, so I used a can of black bean soup (Progresso). I didn't have canned diced tomatoes, so I used a jar of mild chunky salsa (Pace), draining off most of the liquid. I added a tsp of dried cilantro, and chopped up pepper jack cheese slices. I will save this in my favorites recipe folder, I will make this again. I calculated svg to be under 250 calories.
