In a medium skillet over medium-high heat, add the canola oil. When it is hot, fry the tortillas one at a time until they are lightly browned and crispy, about 2 minutes per side. Drain on brown paper.
In a medium pot, heat the reserved chili.
To serve, put a tortilla on a plate. Top with a quarter each of the chili, cheese, beans, onions and peppers, lettuce, tomatoes and sour cream. Repeat with the remaining ingredients.
