If you purchased a package of tortillas that has more than you need for this casserole, there are several ways to use them up. Corn tortillas freeze well. Just wrap them up with plastic wrap or place them in an air-tight container and freeze for up to 3 months. They will also keep well in the refrigerator for up to a week. And, of course, you can use them to make tacos, nachos, and tostadas! Here are some of my favorite recipes: 1. Crispy Corn Tortilla Quesadillas: We love these so much we eat them at least once a week! 2. Grilled Flank Steak Tacos 3. Shishito Pepper Tacos with Fried Cheese and Chili Cranberry Sauce 4. Mahi-Mahi Fish Tacos with Pineapple Slaw 5. Tequila Lime Vegan Tacos with Cabbage Slaw 6. Crispy Black Bean Tostadas with Enchilada Cream 7. Chili Chicken Nachos with Chimichurri Sauce 8. Adobo Fish Tacos
