2 Portobello mushrooms
2 Tbs canola or olive oil
2 Tbs balsalmic vinegar
3 cloves garlic minced
1/4 tsp salt
Clean mushrooms. In a large Ziploc bag, combine, oil, vinegar, garlic and salt. Seal and shake to mix. Put mushrooms in the bag, toss gently and marinate for an hour.
Remove the mushrooms from the bag and place on a piece of foil and then place foil on a baking sheet. Either grill for about 10 minutes (put foil on the grill) or bake in the oven (put baking sheet in the oven) for 10 minutes. Serve immediately while warm.
