Bean and Cheddar Cheese Quesadillas

Step 1

Melt 1 tablespoon of the butter in a large skillet, over medium-high heat, with the cumin, coriander, and toast the spices until fragrant, about 30 seconds. Add the beans and mash with a potato masher into a thick paste. Mix in 1/2 teaspoon salt and transfer to a bowl. Rinse and dry the skillet.

Step 2

Lay out half the tortillas on a work surface. Spoon and spread the beans evenly onto the tortillas. Scatter the cheese evenly over the beans, and top with the remaining tortillas.

Step 3

Halve, seed and dice the avocado. Toss with the tomato and season with salt and pepper, to taste.

Step 4

Melt about 1/2 tablespoon of the butter over medium heat in the skillet. Cook the quesadillas one at a time, until golden and the cheese melts, about 1 1/2 to 2 minutes per side. (Add a bit more butter, if needed when they are turned.) Transfer to a cutting board and cool briefly before cutting into wedges. Serve warm with the avocado mixture and the sour cream, if desired.
