I just threw together a quick dish. I took some fresh beefsteak tomatoes I had in abundance, took the seeds out, and chopped them, with chopped red and orange pepper, Vidalia onion, and zucchini. I mixed with salt, pepper, paprika, oregano, mixed Italian herbs, fennel, minced garlic, and have them roasting on 400 with some olive oil cooking spray.
When it comes out, I will mix most of the roast with pasta for my family, and I will have some of the roasted veggies atop some salad greens with a twist of lemon and some Balsamic for a really low calorie dinner (no more than 100-150).
