Add 2 tbsp olive oil to a skillet over medium heat.

Add prepared mushrooms, peppers, onion, jalapeño and sauté for 5 minutes.

Add 1 tbsp minced garlic, 1 tsp salt, 1 tsp black pepper, 1 tsp smoked paprika, 1 tsp cumin, 1 shot of tequila and juice from 1/2 lime. Sauté for 3 minutes.

Add spinach and cook down until all vegetables are tender and well incorporated with seasonings, approximately 5 minutes.

Place cooked vegetables on to a plate and set aside.

Beef Tenderloin:

Slice your tenderloin steaks into 1-2" long, thin strips.

Place tenderloin strips into a ziplock bag.

Add 2 tbsp olive oil, 1 tsp salt, 1 tsp black pepper, 1 tsp paprika, 1 tsp cumin, 1 tsp garlic powder, 1 tsp onion powder.

Mix well with your fingers to coat tenderloin strips. Let marinate for 2 hours in the refrigerator.

Bring marinated tenderloin strips to room temperature, approximately 1 hour.

Add 2 tbsp butter to the same skillet and drippings from the vegetables.

Saute tenderloin strips for 2-3 minutes, turning to brown all sides.

Remove tenderloin strips to a plate and set aside.

To assemble & cook quesadillas:

Add 1 tbsp butter to a clean skillet, spread evenly, heated to medium heat.

Add tortilla, then a handful of freshly shredded cheese, then some of the vegetable medley.

Add generous portion of beef tenderloin, then additional shredded cheese.

Lay the second tortilla on top.

Turn quesadilla with a wide spatula and brown on both sides until cheeses are melted.

Remove quesadilla from the skillet and place on to a cutting board.

Cut into quartered triangles with a sharp knife or pizza cutter.

Repeat with remaining quesadillas.

For the avocado:

Place 3 large, seeded, peeled and diced avocado into a bowl. Add 2 tbsp olive oil, 1 tsp salt, 1 tsp black pepper, 1/2 cup cilantro, juice from 1/2 lime, 1 tsp cumin. Mix well.
