Cheesy Egg Quesadilla with Spinach

Heat 1 teaspoon oil in a small nonstick skillet over medium-high heat. Add spinach and cook, stirring, until wilted, about 1 minute. Top 1 tortilla with 2 tablespoons cheese, the spinach and the remaining 2 tablespoons cheese. Cover with the other tortilla.

Heat the remaining 1 teaspoon oil in the pan over medium-high heat. Add the quesadilla and cook, flipping once, until crispy, about 4 minutes. Transfer to a plate. Crack egg into the pan and cook until the white is set, about 4 minutes. Top the quesadilla with the egg and avocado. Serve with hot sauce, if desired.
