Portobello Burgers

Ingredients

Wash and pat dry mushroom caps. Paint the top of the caps with a thin layer of olive oil. Fill caps with cheese. Place on hot grill, cheese up, then reduce heat to medium-low. Use direct heat. Musrooms are done when liquid is visible or caps have softened, 15-20 minutes. Cheese may not be runny, but will be softened.

Toast buns; spread a very small amount of mayo on the bottom halves.

Place mushrooms between bun halves, cut in half, and serve.

Serves 2. Obviously, multiples work fine.

Variations
Mozzarella cheese works OK, too, as does cheddar or mixtures.
