Heat the olive oil in a large skillet over medium heat. Once heated, add in the onion and jalapeno and cook until onions begin to soften, about 2 minutes. Then, add in the garlic, season with salt and pepper and cook for 30 seconds. Then, add the tomato paste and stir to combine for about 1 minute. Then, add in the taco meat and crush the tomatoes by hand (from the canned tomatoes) and stir to combine and cook for 2 minutes or until heated through. Fold in the corn and let cook for 30 seconds to heat.
