Cook the ground beef. To a frying pan, over medium-high heat, add the oil. Once the oil is shimmering and hot, add the beef and sauté, breaking it down with a spatula. Once the beef is no longer pink, and the water it released has evaporated, add salt, pepper, garlic powder, paprika, cumin, chili powder, and tomato paste, and cook for 30 seconds, stirring. Turn the heat down to medium and add two-thirds cup of water. Cook until the liquid has mostly disappeared (about 7 more minutes), stirring occasionally.
Get everything ready to assemble the burritos: the cooked ground beef, the cilantro lime rice, the shredded cheese, the drained canned black beans, the pico de gallo, the guacamole, the sour cream, and the tortillas.
Assemble the burritos. To each tortilla, add: the cilantro-lime rice (1/4 cup), the cooked ground beef (1/3 cup), the drained canned black beans (2 tbsp), the shredded cheese (1/4 cup), the pico de gallo (1 1/2 tbsp), the sour cream (1 tbsp), and the guacamole (2 tbsp).
Fold the bottom end of the tortilla over the fillings, then the sides over that, and finally roll forward until you form the burrito.
