Ingredients

For the mushroom fajitas

  • 4 large portobello mushroom caps cleaned and sliced into ½-inch strips
  • 3 bell peppers various colors, sliced
  • 1 large red onion sliced
  • ¼ cup olive oil divided
  • 3 tablespoons fajita spice mix divided
  • 1 lime juiced

For the spiced black beans

  • 1 tablespoon olive oil
  • ½ cup red onion diced
  • 1 poblano pepper diced
  • ½ jalapeño diced with seeds and ribs removed
  • 2 cloves garlic minced
  • 1 teaspoon kosher salt
  • 1 teaspoon ground cumin
  • ½ teaspoon smoked paprika
  • 1 teaspoon chili powder
  • 1 cup vegetable broth
  • ½ lime

Instructions

Make the Mushroom Fajitas

  • Preheat oven to 450 degrees F and line two large baking sheets with foil.
  • Mix together 3 tablespoons olive oil, 2 tablespoons fajita spice mix and juice of 1 lime in a large bowl. Add sliced mushrooms and toss to coat. Let marinate for 10 to 15 minutes, tossing occasionally.
  • Once marinated, divide mushrooms between two baking sheets. Add sliced peppers and onions to the marinate bowl with 1 tablespoon olive oil and 1 tablespoon fajita spice. Toss to combine and divide among sheet pans with mushrooms, spreading to a single layer.
  • Roast for 25 minutes, rotating pans halfway through.

Make the Spiced Black Beans

  • Meanwhile, prepare the black beans by heating 1 tablespoon olive oil in a medium pot. Add diced red onion, poblano and jalapeño and cook on medium-high heat for about 5 minutes.
  • Add minced garlic and spices, cooking 1 more minute. Add in black beans and broth, stirring and bringing to a boil. Once boiling, reduce heat to medium and continue cooking until liquid is cooked off, about 15 minutes.
  • Squeeze juice of ½ lime into beans and serve with Portobello Mushroom Fajitas and Whole30 compatible toppings of your choice – sliced avocado, sliced jalapenos, fresh cilantro and lime wedges.
