Step 1

Preheat the oven to 400F  (or preheat grill to medium)

Step 2

Heat oil in an extra-large skillet over medium-high heat. Add the onion and garlic, saute 3-4 minutes until fragrant. Lower heat to medium, and add the chopped veggies and salt. Stir occasionally until the veggies soften (check) and release their liquid, about 10 minutes (lower heat if need be). Add the oregano, cumin, coriander, chili powder and give a good stir. Add the chopped greens and black beans and a couple of tablespoons of water, and stir until the greens wilt 1-2 minutes. Turn heat off. Stir in optional cilantro and lime zest.

Step 3

Scatter 1/2 cup cheese over the whole tortilla. Add one cup of veggie filling over half of the tortilla. Fold the Tortilla in half so the filling is encased with cheese (see photo). Brush the outer side of the tortilla with oil, and place in a hot oven for 15 minutes. You can place the greased quesadilla directly on the oven grates, or on a parchment-lined sheet pan, flipping halfway through. Bake until tortilla is crispy and cheese is melty.

Step 4

Cut each into 4 pieces and serve with the Spicy Sour Cream and Pico De Gallo

Step 5

To make the spicy sour cream- simply mix a few tablespoons of hot sauce with the sour cream in a little bowl.
