How to Make Grilled Portobello Mushroom Burgers

Prepare the marinade by combining olive oil, balsamic vinegar, soy sauce, garlic, smoked paprika, oregano, black pepper, salt, and lemon juice in a bowl.
Place the mushroom caps into the marinade and coat both sides evenly.
Allow the mushrooms to marinate for at least 20 to 30 minutes. For deeper flavor, you can marinate them for several hours in the refrigerator.
Preheat the grill to medium-high heat.
Place the mushrooms on the grill with the smooth side facing down.
Cook for about 5 to 7 minutes on each side until they become tender and develop beautiful grill marks.
During the final minutes of grilling, add cheese if desired and allow it to melt.
Toast the burger buns lightly on the grill.
Assemble the burgers by adding sauce, lettuce, grilled mushroom caps, tomatoes, onions, avocado, and any additional toppings.
Serve immediately while warm.
The result is a juicy, flavorful vegetarian burger with incredible smoky taste.
