There is nothing like a thick, juicy steak with a portobello mushroom on the side, or even better, a portobello mushroom sandwich. If you're not quite sure how to make the mushroom as tender as your steak, don't fret. Here is a great recipe that will teach you how to roast portobello mushrooms.

Difficulty: Easy

Instructions

Things You'll Need:

1/2 cup olive oil
6 portobello mushrooms
1/4 cup balsamic vinegar
1 tsp. pepper
2 tsp. salt

Step 2
