• Heat a a little oil in a large nonstick skillet or cast iron pan over medium heat, or a low camp fire.
• Add ground meat and chopped onion to the pan and cook - breaking up with a spatula - until the ground meat is browned all around, and onion has softened.
• Add water and taco seasoning to the pan, stir well to combine.
• Continue cooking until the water has cooked off, and has become more of a thick glaze, than a liquid sauce.
• Remove meat from heat, and assemble your tacos:

For Walking Tacos:

• Squish each bag of tacos a couple times to lightly break up the chips a bit.
• Use scissors or a sharp knife to cut a slit in the side of each bag of Doritoes, from top seam to bottom seam.
• Scoop ¼ of the hamburger into each bag of chips, then top with cheese, lettuce, sour cream, salsa, and toppings, as desired.
• Serve immediately!

For Traditional Campfire Tacos:

• As the water is simmering off the taco meat, heat your tortillas a bit. You can microwave them (if in an RV), fry them in a separate pan, or heat them over indirect heat, via the fire.
• Once the taco meat is ready, divide it between the heated tortillas, and top with cheese, lettuce, sour ceam, salsa, and toppings, as desired.
• Serve immediately.
