Peel and chop both sweet potatoes and potatoes. Boil in salted water until soft. Drain and mash. Pre-heat oven to 420°F.
Chop red pepper and coat with 1 teaspoon of oil. Spread on a cookie sheet and cook for 10 to 20 minutes, or until peppers soften and begin to brown.
Add red pepper, jalapeno pepper, coriander, carrot, salt, cumin and ⅔ cup of the breadcrumbs to the mashed potatoes. Stir well. Shape into thin patties. Coat with leftover breadcrumbs.
Heat the oil in a sauté pan. Fry into until golden on both sides.
Serve as a usual burger, best on buns. My burger was topped with lettuce, tomato, pickles, grapeseed veganaise.
