Caramelized Onion and Jalapeño Quesadillas

Ingredients

• 1 tablespoon butter
• 1 large onion, chopped
• 2 jalapeño peppers, chopped
• 2 tablespoons vegetable oil, or as needed
• 4 (10 inch) flour tortillas
• 1 cup shredded Mexican cheese blend

Instructions

1. Melt butter in a large skillet over medium-low heat. Add onion; cook and stir until softened and lightly browned, about 10 minutes. Add jalapeño peppers; cook and stir until onion is browned, about 10 more minutes. Transfer mixture to a plate.
2. Heat about 1 tablespoon oil in the same skillet. Add one tortilla; top with 1/4 cup cheese, 1/2 of the onion mixture, and another 1/4 cup cheese. Top with another tortilla and cook quesadilla until browned and cheese is melted, 1 to 2 minutes per side. Remove to a plate, add more oil to the skillet, and repeat to make remaining quesadilla.
