These aren't exactly low cal, hence why I don't cook them often, but I try to cook them as healthily as possible by doing my own salsa (recipe here) and guacamole.
Ingredients for a bowl:
2 tomatoes (deseeded and chopped) - I only had cherry tomatoes and I was too lazy to deseed!
1 tbsp lime juice
1 tbsp coriander, chopped
Add a spoonful of lime juice.
Add a spoonful of coriander.
Chop the tomatoes and remove the seeds (if you can be bothered).
For the tacos, I used a taco spice mix, minced beef, tortilla wraps, sour cream, salsa, lettuce and lots of grated cheese!
And here was the end result!
