Ingredients

4 large portobello mushrooms, stems and gills removed (see Tip)
3 tablespoons extra-virgin olive oil, divided
1 cup thinly sliced onion
3 cups thinly sliced bell peppers
½ teaspoon ground pepper, divided
¼ teaspoon salt, divided
8 ounces beef strip loin, thinly sliced
3 ounces sliced provolone cheese
Chopped parsley for garnish

Directions

Preheat oven to 350 degrees F. Place mushroom caps on a large rimmed baking sheet and brush all sides lightly with 1 tablespoon oil. Arrange the mushrooms stem-side up.
Heat 1 tablespoon oil in a large skillet over medium heat. Add onion and cook, stirring, until starting to soften, about 3 minutes. Add peppers, 1/4 teaspoon pepper and 1/8 teaspoon salt; cook, stirring, until the peppers are softened, 4 to 5 minutes. Transfer the vegetables to a plate.
Season beef with the remaining 1/4 teaspoon pepper and 1/8 teaspoon salt. Heat the remaining 1 tablespoon oil in the skillet; add the beef and cook, stirring, until browned on all sides, 2 to 3 minutes. Return the vegetables to the pan and stir to combine. Fill each of the prepared mushrooms with about 3/4 cup filling and top with 3/4 ounce cheese. Bake until the mushrooms are tender and the cheese has melted, 12 to 15 minutes. Sprinkle with parsley before serving, if desired.

Tips

Tip: To prepare portobello mushroom caps, gently twist off the stems of whole portobellos. Using a spoon, scrape off the brown gills from the underside of the mushroom caps. If you prefer, purchase portobello mushroom caps, rather than whole mushrooms.

Nutrition information is calculated by a registered dietitian using an ingredient database but should be considered an estimate.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
