Ingredients

  • 4 large  Portobello mushrooms, stems and gills removed
  • 4 tablespoons butter, melted
  • 5 cloves garlic, minced, divided
  • 1 tablespoon olive oil
  • 1 small yellow onion, finely chopped
  • 1 cup finely diced bell pepper, any color pepper
  • 1 can (15-oz) black beans, rinsed and drained
  • 1 can (15-oz) corn kernels, rinsed and drained
  • Salt and pepper to taste
  • 1/2 tablespoon taco seasoning
  • 1/2 teaspoon chili powder, to taste
  • 3/4 cup Mexican blend shredded cheese
  • Fresh cilantro or parsley, chopped, for garnish

Instructions

  • Preheat oven to 400˚F.
  • Carefully remove the stems from the mushrooms and gently remove the brown gills from inside the mushroom caps. Wash the mushrooms and dry with paper towels; set aside.
  • Melt butter; then, whisk in half of the minced garlic and chopped parsley. Brush the garlic-butter all over the mushrooms.
  • Transfer mushrooms to a baking sheet and bake for 8 to 10 minutes, or until tender. 
  • In the meantime, prepare the filling: Heat a tablespoon of olive oil in a frying pan set over medium-high heat. Add onions to the heated oil and cook for 1 minute.
    Stir in diced bell peppers and continue to cook for 2 to 3 minutes, or until just tender. Stir in remaining garlic; cook for 20 seconds.
  • Add black beans and corn and season with salt, pepper, taco seasoning and chili powder.
    Continue to cook for 2 minutes, or until heated through. 
  • Remove mushrooms from oven.
  • Divide up the prepared corn mixture between all 4 mushrooms.
  • Add shredded cheese over each mushroom.
    Return back to the oven and cook for 10 to 12 more minutes, or until cheese is melted. 
  • Remove from oven.
    Top with chopped cilantro or parsley.
    Serve.
