Remove the husks and silk from the ears of corn. Brush a grill pan lightly with oil and char over medium high heat, about 6 minutes.
While corn is charring, add the remaining ingredients (except cilantro) to a crock pot on low heat.
Once corn is charred, let the corn cool, cut the kernels off the cob and add to the crockpot.
Stir occasionally to blend the ingredients and prevent the cheese from burning.
Once warmed, serve with tortilla chips.
