Let kids help with the simple steps in bold!
- 4 large portobello mushroom caps, wiped clean and dried (not rinsed)
- 3 tablespoons balsamic vinegar
- 1 teaspoon Dijon mustard
- 1 teaspoon vegetable oil
- 2 garlic cloves, minced
- salt and pepper to taste
- whole wheat hamburger buns
- toppings of your choice
Step 1: Whisk the vinegar, mustard, garlic and oil together in a small bowl, then use a basting brush to apply it on both sides of the portobello caps. Add salt and pepper to taste.
Step 2: Arrange portobello caps, gills down, on the grill or on a broiler pan.
Step 3: Cook about 6–8 minutes, then turn and cook an additional 4–8 minutes or longer until tender and juicy (time varies depending on mushroom thickness).
Step 4: Serve on a bun with your favorite toppings. Try: spinach leaves, tomato, onion, pickles, chopped olives, avocado, roasted or raw bell pepper, feta or pesto.
