Add a small amount of olive oil to a skillet and saute the carrots about 3-4 minutes, then add the yellow or green pepper and garlic and saute another minute. Add the reserved zucchini, scallions, tomatoes and herbs, saute another minute or two. Salt and pepper to taste.
Stuff the zucchini with the rice mixture and place in a baking dish. I added a little water in the bottom of the baking dish, bake at 375 degrees for 30 minutes
