                Pour 1 tbsp oil into a big frying pan on medium-high. Throw in grated potatoes, add some salt and pepper, and cook till they're golden and crunchy, about 2-3 minutes each side. Set them aside on a plate.

                In a bowl, stir together the cleaned black beans with half a cup of the ranchero sauce and put it aside.

                In the same pan, warm the leftover oil on low heat. Lightly scramble the eggs until barely set – they'll finish cooking later in the oven. Add them to your bean mix along with the crispy potatoes, salt, and 1 tbsp of cilantro. Stir everything together.

                Get your oven hot at 350°F. Spray some cooking oil in a 9x13 baking dish and spread a bit of ranchero sauce on the bottom. Fill each tortilla with your egg-bean mixture, roll them up, and place them in the dish with the seam facing down. Pour the remaining sauce on top and sprinkle with cheese. Bake for 10-15 minutes until the cheese gets bubbly. Sprinkle the rest of the cilantro on top before serving.
