Ingredients for ~6:
Tortillas, white (6)
Texmex cheese mix
I used 500g mixed ground pork and beef. Just beef is probably better but beef+pork mix is cheaper.
Jumbo nondescript "taco seasoning" 25g
4 Roma tomatoes diced
1 large white onion diced
1 Cayenne pepper finely chopped
100g sour cream
100g shredded iceberg lettuce
Nacho chips (an amount)

Instructions:
Fry ground meat + cayenne pepper + white onion in pan
Once meat browned add taco seasoning and mix in
Add ingredients to middle of tortilla: meat mix+onion+chilli, followed by 1 spoonful sourcream
Layer around 4 nacho chips on top
Followed by lettuce and tomatoes and cheese
A good place to add some extra sauce if you want it would be atop the nacho chips. I added some tobasco.
Fold closed in the following manner: Top+bottom, then CORNERS, then sides
Fry in olive oil seam down for like 90 seconds, then flip and fry the non-seam side for another 60

Nacho cheese would also be a nice addition if you can find it and like it. My partner doesn't, so I didn't add it. I would spread this on underneath the meat mix.

Roma tomatoes come highly recommended for dicing in this situation. Not too watery like other tomatoes I've tried.
