Grease a 9×13 baking dish with cooking spray and preheat the oven to 425°F. Place aside.
Set a skillet over medium-high heat, add the olive oil, and allow it to heat up.
Stir in the ground beef, chili powder, coriander, salt, pepper, and cumin. Break the beef up with a wooden spoon and cook for 5 minutes, stirring occasionally.
Then, add the black beans, corn kernels, red onion, garlic, and red pepper, and cook for a further 5 minutes.
Reduce the heat and add the salsa then simmer for 7 minutes.
Using slightly overlapping tortillas, line a previously prepared baking dish.
Taste the beef mixture for salt and adjust as necessary.
Spread 1/3 of the beef mixture on top of the tortillas and spread evenly.
Over the beef, sprinkle 1/3 of the shredded cheddar cheese.
Repeat this layering process two more times, ending with cheese.
Bake for 20 to 25 minutes, or until bubbly and hot.
Take the baking dish out of the oven and let it stand for 10 minutes before serving.
