Balsamic Portobello Burgers

Serves: 4

Ingredients:
1/4 cup balsamic vinegar
1/4 cup olive oil
2 tbs lemon juice
1 tbs dijon mustard
1 tbs minced garlic
1 tsp minced thyme
4 portobello mushrooms
Salt and pepper to taste

Directions:
Remove stems and gills from the mushrooms (a spoon works well for this) and scrub clean.
In a bowl whisk together vinegar, oil, lemon juice, mustard, garlic, thyme, some salt, and some pepper.
Place mushrooms in a resealable plastic bag and pour marinade over top.
Seal bag and toss to coat. Leave at room temperature to marinate for 30 minutes, toss occasionally.
Place mushrooms on a medium heat grill for 5 minutes each side until fully cooked.
Serve on a whole grain bun with kale, red onions, and tomato. Enjoy!
