Drain half of the liquid from each can of beans. Add the beans, half of a jalapeño that has been diced, and taco seasoning to a cast-iron skillet. Put the skillet over a low fire pit flame or medium heat on the stove.
Stir the beans occasionally as they cook for 10 minutes. While the beans are cooking, prepare all of the other toppings. Slice the limes, avocados, and jalapeños. Dice the tomatoes, lettuce, onions, and cilantro.
After the beans have cooked for 10 minutes, mash them with a fork to your desired consistency. If the beans are too thick, you can stir in some water. Continue to cook for 5 more minutes.
Gently crush the chips while the bags are still closed. Cut or tear one end of each bag. Layer the beans and any other desired toppings right into the chip bags. Enjoy your walking taco with a fork as you walk around!
