Mince the garlic. Cut the tomatoes in half, then thinly slice. Cut the onions, peppers, and celery into slivers.
Cut the chicken into bite-sized pieces, season with salt, pepper, and sake.
Heat oil in a pan, fry the onions, then add the garlic. Add the chicken and fry.
Add all the veggies and cayenne powder and fry. Season again with salt and pepper to taste.
Once everything is cooked, it's done. (The tomatoes will simmer down.)
