Make The Crema. Add 1 teaspoon of the taco seasoning to the sour cream, along with 1 Tablespoon fresh lime juice. Stir to combine until the mixture is evenly blended.
Cook The Chicken. Next, cook the chicken. Heat olive oil in a medium skillet and add ground chicken. Cook the chicken through, then add the remaining taco seasoning, lime juice, cilantro, and any water that your taco seasoning calls for. (Siete recommends 1/3 cup water) Cook an additional 1-2 minutes, until thickened and evenly coated in seasoning. Set chicken aside.
Warm Tortillas In Batches. Working in batches, warm 2-3 tortillas between layers of slightly damp tortillas in the microwave in 10-20 second bursts until they're soft and pliable.
Build Burritos. Layer each tortilla with about 1/4 cup refried beans, 1/8 of the chicken mixture, 1 Tablespoon crema, and 1/4 cup cheddar cheese. Fold the burritos, by folding in the tops and bottoms of the burrito in slightly, then rolling them up. (see video, if needed, for a visual!)
Crisp Burritos. Preheat a large skillet over medium-low heat. Place burritos seam side DOWN in the warm skillet and cook 2-4 minutes per side, until golden brown. Remove and place on a plate or wire rack and repeat until all burritos are cooked.
Serve & Store. Enjoy burritos warm with the rest of the crema, some salsa, or guacamole. Store leftover burritos in an airtight container in the fridge 1-2 days, or freeze individually wrapped and stored in an airtight bag in the freezer up to 2 months.
