PREP TIME: 1 hours 0 minutes
COOK TIME: 15 minutes

For the pickled onions:
1 large red onion, very thinly sliced int half-moons
1 cup white or red wine vinegar
1/2 cup white sugar

For the mushrooms:
2-3 large portobello mushrooms, brushed clean and stems removed
2 tablespoons canned chipotle in adobo sauce
2 teaspoons soy or tamari sauce
1 tablespoon neutral flavored oil
1 clove garlic, minced

Remaining ingredients:
4 flour or corn tortillas
1/2 avocado, pitted, peeled and sliced
1/2 jalapeño, thinly sliced
Chopped fresh cilantro or parsley and sour cream, for garnish

Make the pickled onions: Pack onions into a 32 ounce glass jar with a lid. Bring sugar and vinegar to a simmer on the stove top. Do not boil the mixture -- you only want to dissolve the sugar. Once the sugar has dissolved, pour vinegar mixture over the onions. Let stand, uncovered for an hour then put the lid on and let sit at room temperature for at least 4 hours before serving.

Marinade the mushrooms: Place mushrooms, gill side up, in a small baking dish. Whisk chipotle in adobo, garlic, soy and oil together. Pour over mushrooms. Let mushrooms sit at room temperature for an hour.

Once mushrooms have marinated, preheat your grill or grill pan to medium-high and oil the grill. Remove mushrooms from marinade ad shake off excess marinade. Cook mushrooms for 5-6 minutes, flipping once in the middle of cooking. Once mushrooms have browned on the outside and are fork-tender, remove from heat and let stand for a few minutes before slicing.

To assemble the tacos, heat tortillas on grill for a few seconds. Place a tortilla on your work surface, and add some sliced mushrooms, a scoop of onions, sliced jalapeño and some avocado. Top with cilantro and sour cream. Serve right away.
