I felt like something tasty for lunch that wouldn't take long to make, and came up with this. It had good flavour and could be even better with some texture added, so I will try adding fried red onion next time and maybe tuna. I used half an avocado on one small tortilla, but it would have spread to three of four. Give it a try if you're feeling peckish and want something fast. I didn't bother grating the cheese, just ripped it into a few shreds and let the heat melt it. It couldn't have been easier to make and would have taken less than ten minutes from start to finish. I like my tortillas crisp. If you like yours soft, turn the heat down. Cooking time will be three or four minutes longer. Update: I made this again, adding red onion. It improved the texture and flavour, so I am editing this recipe to include onion and adjusting the cooking time slightly.
