This was going to be a succotash, but then it changed. :-)
Cook diced onion and chopped garlic in olive oil with a good pinch of salt until the onion starts to soften, add diced carrot and cook a few minutes. Add diced long-green pepper and cook another five or so minutes. Add diced summer squash and some more salt and cook, covered, until the squash is almost ready to eat. Add fresh corn and cook another couple of minutes.
Sometimes it's really nice to just have a big plate of well-cooked fresh vegetables.
We ate the veggies with oven-roasted potato wedges and a big green salad.
