kosher salt and freshly ground black pepper, to taste
4 large flour tortillas
8 ounce queso blanco, cotija, or jack cheese, crumbled or shredded
guacamole, to taste
Directions
Combine all of the ingredients in the bowl of a food processor and process until combined.
In a pot, heat the beans with their liquid just until warmed through. Meanwhile, heat the vegetable oil in a sauté pan over high heat and add the shrimp. Season with salt and pepper, to taste. Sauté just until the shrimp are opaque, about 2-3 minutes, and remove from the heat.
Drain the beans in a colander. Warm a tortilla in a dry skillet for about 10-15 seconds on each side. Place the tortilla on a sheet of aluminum foil and spoon some beans onto the tortilla, forming a rectangle across the center of the tortilla. Top with some cheese, followed by the shrimp, salsa (not too much or your burrito will be soggy), and guacamole.
Roll the burrito. Pull up the sides and gently bring them toward the center to make two flaps. Grasping the bottom end of the tortilla with your thumbs and forefingers, gently roll the tortilla and fillings forward together, using your other fingers to maintain a burrito shape. Take the corners that form at the top end, tuck them under, and roll. Try not to squeeze too much. (Don't feel bad if you don't get it the first time, or second, or third; practice makes perfect.)
