In a microwave-safe dish, add water to beanflakes and microwave on high for 1 minute.
Spread rehydrated bean flakes on half the corntortilla and top with cheese.
When the oliveoil has heated, gently place the tortillas with beans and cheese in the pan. After a few seconds, when the tortilla has softened, fold the unfilled half of the tortilla over. Fry until golden and crispy. (1-2 minutes) Turn taco over and fry until that side is golden and crispy. (1-2 minutes)
Cover a plate with paper towels, remove the tacos and place them on the paper towels to absorb the excess oil.
Place the tacos and selected sides on a plate. Serve.
