Cut the washed and peeled zucchini into wheels. Wash, clean and chop the mushrooms into thin strips, and onions - into cubes. Slice the chili peppers into round slices and the red pepper finely.
Add a little water and sprinkle the dish with salt and pepper to taste. Place in a microwave oven and put it on the grill setting at 600 W for about 10 minutes.
