Preheat a large skillet over medium heat for one minute. Add olive oil and butter. When the butter is melted, sauté the onion for 1 minute. Add the garlic, chili, and continue mixing for one more minute. Add the mushrooms, salt, pepper, and continue cooking for 4-5 more minutes. Remove from heat, add the epazote.
Preheat a nonstick skillet over 2 mins over high heat. Heat the CAULIPOWER Cauliflower Tortilla for 15 seconds. Flip the tortilla and add a little of the mushroom stew and quesadilla cheese. Fold the tortilla in half. Cook the quesadilla for 2-3 minutes or until cheese melts over low heat until the CAULIPOWER Cauliflower Tortilla is lightly browned. Flip the quesadilla as necessary while the cheese is melting to prevent burning. Repeat the steps with the remaining ingredients. Serve with your favorite sauce.
