Step-by-Step Instructions
Preparation Steps
Prepping the Grill
First, you need to heat your grill or grill pan. Set it to medium heat. You want it hot enough to sear but not smoking. This helps cook the mushrooms evenly and gives them a nice char.
Mixing the Filling
In a large bowl, combine the following ingredients:
- 1 cup cooked quinoa (cooled)
- 1 cup fresh baby spinach, finely chopped
- 1/2 cup sun-dried tomatoes, diced
- 1/2 cup feta cheese, crumbled
- 1/4 cup red onion, finely chopped
- 3 cloves garlic, minced
- 1 teaspoon dried oregano
- 1 teaspoon balsamic vinegar
- Salt and freshly cracked pepper, to taste
Mix these well. Make sure everything is evenly distributed. The flavors blend nicely this way.
Stuffing the Mushrooms
Take each Portobello mushroom cap. Brush both sides with olive oil. Season the inside with salt and pepper. This adds flavor. Now, fill each cap with the quinoa mixture. Press it down gently. You want the filling packed snugly.
Grilling Instructions
Place the stuffed mushrooms gill side up on the grill. Cover and cook for 5-7 minutes. Check for tenderness and a light char. Then, flip each mushroom cap. Grill the other side for 3-4 minutes. Watch closely to avoid burning.
While grilling, toast your whole grain burger buns on the grill until golden brown.
Once done, assemble your burger. Place the grilled mushroom on the bottom bun. Add fresh basil leaves on top. Finally, add the top half of the bun. Enjoy your delicious creation!
