• Wash the portobellos well. Cut off the stems and remove the gills with a spoon. Pat the insides dry and brush or spray both sides with balsamic vinegar. Sprinkle the inside with salt and pepper.
  
• Spread 1 tablespoon of pasta sauce inside each mushroom and sprinkle it with garlic. 

Air Fryer Instructions

• Preheat the Air Fryer to 330F. Place as many mushrooms as will fit in a single layer or use a rack to hold two layers. (You may need to do this in batches, depending on the size or your air fryer and portobellos.) Air Fry for 3 minutes.
• Remove mushrooms and top each one with equal portions of zucchini, peppers, and olives and sprinkle with dried basil and salt and pepper. Return to the Air Fryer for 3 minutes. Check mushrooms and rearrange if using a rack. Return to the Air Fryer for another 3 minutes or until mushrooms are tender. Place on a plate, drizzle with hummus and sprinkle with basil or other herbs.  If you want, you can put the portobellos back into the air fryer briefly to warm the hummus.
  

Oven Instructions

• Preheat oven to 400F. Place the sauced portobellos in a baking dish and bake for 5 minutes. Remove from the oven and top each one with equal portions of zucchini, peppers, and olives and sprinkle with dried basil and salt and pepper. Return to the oven and cook until mushrooms are tender, abut 15 minutes. Place on a plate, drizzle with hummus and sprinkle with basil or other herbs. If you want, you can put the portobellos back under the broiler briefly to warm the hummus.
