Ingredients for Grilled Portobello Burger with Onion Jam

• 4 large portobello mushroom caps, cleaned and stems removed
• 2 tablespoons olive oil
• 2 tablespoons balsamic vinegar
• 1 teaspoon garlic powder
• Salt and pepper to taste
• 4 whole-grain burger buns
• Lettuce, tomato slices, and avocado (for toppings)

For the Onion Jam:

• 2 large onions, thinly sliced
• 2 tablespoons olive oil
• 2 tablespoons brown sugar
• 1/4 cup balsamic vinegar
• Salt and pepper to taste

Step-by-Step Instructions

Step 1: Prepare the Onion Jam

1. Sauté the Onions: In a large skillet, heat the olive oil over medium heat. Add the thinly sliced onions and a pinch of salt. Sauté the onions for about 10-15 minutes, stirring occasionally, until they become soft and translucent.
2. Caramelize the Onions: Add the brown sugar to the skillet and continue to cook the onions for another 15-20 minutes, stirring frequently. The onions should turn a deep golden brown and become caramelized.
3. Add Balsamic Vinegar: Once the onions are caramelized, pour in the balsamic vinegar and stir to combine. Cook for an additional 5 minutes until the vinegar has reduced and the mixture is thick and jam-like. Season with salt and pepper to taste. Remove from heat and set aside.

Step 2: Marinate the Portobello Mushrooms

1. Prepare the Marinade: In a small bowl, whisk together the olive oil, balsamic vinegar, garlic powder, salt, and pepper.
2. Marinate the Mushrooms: Place the portobello mushroom caps in a shallow dish and pour the marinade over them, ensuring they are well coated. Let them marinate for at least 30 minutes to absorb the flavors.

Step 3: Grill the Portobello Mushrooms

1. Preheat the Grill: Preheat your grill or grill pan over medium-high heat.
2. Grill the Mushrooms: Once the grill is hot, place the marinated portobello mushrooms on the grill, gill side down. Grill for about 5-7 minutes on each side, or until they are tender and have nice grill marks.

Step 4: Assemble the Burgers

1. Toast the Buns: If desired, lightly toast the whole-grain burger buns on the grill for a minute or two until golden brown.
2. Build the Burger: Start with the bottom half of the bun, add a grilled portobello mushroom cap, a generous spoonful of onion jam, and your choice of toppings such as lettuce, tomato slices, and avocado. Top with the other half of the bun.

Step 5: Serve and Enjoy

Serve the Grilled Portobello Burgers warm with a side of sweet potato fries, a fresh salad, or your favorite dipping sauce. Enjoy the rich flavors and satisfying textures of this delicious plant-based burger!
