In a mixing bowl, whisk together the eggs, a few dashes of hot sauce, and a pinch of salt until fully blended. Stir in the cooked beans gently so they hold their shape. This step infuses flavor into the eggs and preps everything for the skillet. Set this bowl aside while you heat the pan.
Heat 2 teaspoons of butter or olive oil in a medium skillet over medium heat until it starts to bubble. Pour in your egg and bean mixture. Stir gently and often, just until the eggs are barely set—this should take about 1 to 3 minutes. Remove from heat and mix in chopped green onion, cilantro, and jalapeños if using. Set aside; the eggs will finish cooking inside the quesadilla.
Place the whole grain tortilla in a large skillet over medium heat and warm both sides. Once warmed, sprinkle half of the grated cheddar on one half of the tortilla. Spoon the egg mixture on top, then sprinkle the rest of the cheese over it. Fold the tortilla over to cover the filling and press gently. Cook for about 1–2 minutes per side until golden and crispy.
Transfer the quesadilla to a cutting board and let it cool for 2–3 minutes to allow everything to set. Use a sharp knife to cut the quesadilla into two neat slices. Serve immediately with your favorite salsa or more hot sauce. It’s the perfect bite—crispy, cheesy, and full of flavor.
