Pour the salsa, stir, and continue cooking for 2 to 3 minutes, until simering. Gently, crack the eggs, one by one, making room in the salsa with nopalitos. Cover with a bit of the salsa. Cover with the lid and cook until the egg whites are set and the yolks are still runny, about 4 to 5 minutes.
Meanwhile, slice the bread in half, spread refried beans on top, cover with shredded cheese and place in a toaster oven or oven at 350℉ for 7 to 8 minutes until cheese melts and bread toasts. Top with a cooked egg and nopalitos in salsa. Garnish with red onion and queso cotija.
