I had previously made birria tacos and made way more than I needed. So I froze down the leftovers for later use, which led me to now: behold the birria enchilada. The leftover meat was put into a corn tortillas with chunks of mozzarella, then bathed in the birria broth. I topped it off with more cheese and baked it for 20 minutes until the cheese was bubbly. Easily the best enchiladas I’ve ever eaten.
