In a large saute pan heat 2 tablespoons olive oil over medium high heat.
Add the jackfruit, garlic and onion. Use the back of a wooden spoon to break apart the jackfruit.
Cook, stirring constantly until the onions start to break down, about 5 minutes.
Next add the chili powder, cumin and cayenne. Reduce heat to medium low. Stir to coat and add 1/2 cup of water to the pan. Cover and allow to cook for 8-10 minutes stirring occasionally being sure to break up the jackfruit.
Season with salt and pepper. To serve, build tacos by filling tortillas with jackfruit and top with your favorite garnishes.
