In a large bowl, combine the cooked chicken, black beans, corn, red bell pepper, Monterey Jack cheese, green onions, cumin, and chili powder.
Mix everything until well incorporated.
Take an egg roll wrapper and position it on a clean surface in a diamond shape.
Add about 3 tablespoons of the filling to the center.
Fold the bottom corner over the filling, then fold in the side corners.
Wet the edges lightly with water to seal.
Roll the wrapper tightly.
Heat about 1 inch of canola oil in a large pot over medium-high heat.
Carefully place 3-4 egg rolls in the heated oil at a time.
Fry each egg roll until golden brown on all sides, approximately 2-3 minutes per side.
Remove and drain on paper towels.
Serve warm with your favorite dipping sauce!
