  2. ½ cup fresh lime juice
  3. 4 tsp dried oregano
  4. 4 tsp ground cumin
  5. 3 tsp chili powder
  6. 1½ tsp salt
  7. freshly ground pepper

The Rest:

  2. 1 large yellow pepper thinly sliced
  3. 1 large orange pepper thinly sliced

  6. 6-8 whole wheat flour tortillas
  7. 1/2 cup cherry tomatoes, cut in half
  8. Cilantro

  1. Prepare the portobellos. Scrape out gills and remove stems with a small spoon. Wash gently or alternatively wipe with a damp cloth. Slice into long ½ inch wide strips.
  2. Thinly slice peppers and onions
  3. Prepare the marinade by whisking together the grapeseed oil, lime juice, dried oregano, ground cumin, chili powder, salt and freshly ground pepper (to taste).
  4. Add cut mushrooms to one large flat baking dish and peppers/ onion to the other.
  5. Set the pepper/ onion mix in the fridge until later.
  6. Toss the mushrooms well with about ¾ of the marinade. Set the remaining ¼ of the marinade aside for later. Leave the mushrooms marinating for at least half an hour (preferably longer) tossing every 30 minutes as able. Cover and refrigerate.
  7. When you're ready to eat, toss the pepper mix with the remaining marinade. Preheat a large skillet and pour in contents of the bowl containing peppers/onions/ marinade. Saute over medium for about 10 minutes or until veggies are softened.
