Grilled Portobello Mushroom Burgers Recipe

Ingredients (Serves 4)

• 4 large portobello mushroom caps (about 4-5 inches diameter)
• ¼ cup low-sodium soy sauce
• 3 tablespoons balsamic vinegar
• 2 tablespoons olive oil
• 3 cloves garlic, minced
• 1 teaspoon Dijon mustard
• ½ teaspoon fresh cracked black pepper
• 4 whole wheat burger buns
• 4 slices low-fat Swiss cheese
• 1 large tomato, sliced
• 4 leaves butter lettuce
• ¼ cup Greek yogurt (for patriotic burger sauce)
• 1 tablespoon apple cider vinegar
• 1 teaspoon hot sauce (optional, for kick)
• Fresh basil for garnish

Instructions

Step 1: Prepare the Mushrooms
Remove the stems from portobello caps and gently scrape out the dark gills with a spoon. This prevents the burger from becoming waterlogged. Pat the caps dry with paper towels.

Step 2: Make the Marinade
Whisk together soy sauce, balsamic vinegar, olive oil, minced garlic, Dijon mustard, and black pepper in a shallow dish. Place mushroom caps gill-side up in the marinade and let sit for 15-20 minutes, turning halfway through.

Step 3: Prepare the Patriotic Sauce
Mix Greek yogurt with apple cider vinegar and hot sauce if desired. Set aside. This tangy condiment adds 3 extra grams of protein per burger.

Step 4: Grill to Perfection
Preheat grill to medium-high heat (400°F). Place mushroom caps gill-side down on the grill grate. Cook for 4-5 minutes until grill marks appear. Flip, top each cap with a slice of Swiss cheese, and cook for another 3-4 minutes until cheese melts and mushrooms are tender.

Step 5: Assemble Your Burger
Toast the whole wheat buns lightly on the grill. Spread patriotic sauce on the bottom bun, then layer lettuce, grilled mushroom (gill-side up), tomato slice, and top bun. Garnish with fresh basil.
