Preheat oven to 425 F.
On medium heat, heat 1 tbsp of olive oil in a medium-sized frying pan. Add ground beef and begin to break it up with a spatula.
Add salt and pepper and continue to cook, breaking up the meat until it is browned. (about 5 minutes.)
Add the onion and garlic, and cook for about another 5 minutes.
Next, stir in the tomato sauce and taco seasoning.
Stir in the corn and cook for another 5 minutes.
Line a large baking sheet with parchment paper.
Once the meat mixture is cooked, begin spooning into the flour tortillas. Divide half the cheddar cheese over the meat mixture and begin rolling the taquitos up on the baking sheet.
Brush the tops with olive oil and sprinkle with remaining cheddar cheese.
Bake at 425 F for about 15 to 20 minutes until crisp to your liking.
