In a large mixing bowl, combine the cooked chicken, corn, black beans, chopped spinach, diced red bell pepper, and jalapeno.
Add the cumin, chili powder, salt, and black pepper to the mixture. Mix well to ensure that all the ingredients are evenly coated with the spices.
Stir in the Monterey Jack cheese, which will add a creamy texture to the filling.
Place an egg roll wrapper on a clean surface with one point facing you.
Spoon 2-3 tablespoons of the filling into the center of the wrapper. Be careful not to overfill.
Follow the package instructions to roll the egg roll: fold the bottom corner up over the filling, then fold in the side corners tightly, and roll it up to seal. Use a little water to seal the edges if needed.
Repeat the process with the remaining filling and wrappers, placing the rolled egg rolls on a baking sheet.
For frying, heat oil in a skillet to 350°F. Fry the egg rolls for 2-3 minutes on each side until golden brown. Drain them on paper towels to keep them crispy.
For baking, preheat your oven to 425°F. Brush the egg rolls with oil and bake for 15-20 minutes, flipping halfway through, until they are golden and crispy.
Serve with your favorite dipping sauces and toppings.
Notes
For a crispy texture, consider air frying the egg rolls.
