I make fajitas with spray oil, quorn mince, peppers, onion and tomatoes. Salsa just has tomatoes/chilli/peppers and lemon juice. The wraps aren't hugely fattening and you can serve them with salad to bulk it up, and natural yoghurt instead of sour cream. Not the healthiest but I wouldn't say its full of calories. Nachos probably a little bit harder to make healthier though, I agree with that!
