Heat the oil in a nonstick skillet over medium-high heat.
Add the chicken and sauté on each side until browned, about 5 minutes per side. Remove from pan.
Once cool, shred the chicken with two forks. Return to pan and add ¼ cup of water and 2 Tbsp taco seasoning.
Simmer on low heat until hot and bubbly, adding more water if necessary.
In a large bowl, gently mix chips, queso, jalapenos, tomatoes, cheddar cheese and shredded chicken, careful not to break the chips.
Set the tin can on a large plate and stack the chicken mixture inside the can.
Top with the shredded lettuce and sour cream.
When ready to serve, slowly lift off the coffee tin and let the chips fall where they may!
