Marinade
- 2 tablespoons olive oil
- 1 tablespoon balsamic vinegar
- 1 teaspoon yellow mustard
- Salt & pepper
Ingredients
- 2 large portobello mushrooms, sliced into 4 long slices each
Fixings:
- ½ cup chopped red onion
- ½ cup sliced tomatoes
- Squeeze of lime
- Salt & pepper
- Yellow mustard
- 4-5 hot dog buns
- Ketchup on the side
Instructions
- In a separate bowl, mix together the sliced tomatoes and chopped red onion. Add a squeeze of lime, salt and pepper. Stir and set aside.
- Preheat your grill or grill pan. In another small bowl, mix the marinade ingredients together (olive oil, balsamic, mustard, salt & pepper), and brush onto the portobello slices until they’re coated.
- Grill mushroom strips on each side until grill marks form and mushrooms are tender and juicy (about 3-4 minutes per side). Place 2 mushroom slices into each hot dog bun. Top liberally with onion & tomatoes, some serrano slices, and a swirl of mustard.
