Cheesy Bacon Quesadillas

Add bacon to a large dry pan in a single layer; heat over medium-high heat. Cook, turning occasionally, until crispy, 6-10 minutes. Turn off heat; transfer bacon to a paper-towel-lined plate. Wipe out pan. Once cool enough to handle, roughly chop bacon. Lay tortillas on a clean surface. Evenly sprinkle bottom half of each tortilla with cheddar and Monterey Jack. Top with chopped bacon. Fold tortillas in half to create mini quesadillas. Melt 1 TBSP butter in pan used for bacon over medium heat. Add quesadillas and cook until tortillas are browned and cheese melts, 1-3 minutes per side. (You may need to work in batches, adding 1 TBSP butter between each batch.) Cut quesadillas in half. Divide between plates and serve.
