Prepare the tortillas by following this recipe and creating taco shells.

Peel and finely chop the onion and garlic.

Place the onion and garlic on a pan greased with ghee and cook over a medium-high heat until lightly browned.

Stir to avoid burning.

Add the ground beef and cook until browned from all sides while mixing.

I buy ground meat in bulk from my local farmer (here are more tips on how to save time & money on a keto diet).

Add the chili powder and ground cumin.

If you don't have any of these, use 1 1/2 tsp of paprika.

Add the tomato puree and pour in the water.

Season with salt and pepper.

Mix until well combined and cook until the sauce has reduced to about a quarter and the meat is cooked through.

When done, set aside and prepare the vegetable topping.

Wash and dry all the vegetables on a paper tissue.

Halve, deseed, peel and chop the avocado and chop the tomatoes and lettuce.

Start filling the taco shells (recipe is here - follow instructions for taco shells).

Start with the meat mixture and top with tomatoes...

avocado and lettuce.

Optionally, add other toppings (grated cheddar cheese, soured cream, etc.) Enjoy! Instead of taco shells, you can make nachos (recipe is here) and serve the meat as a dip.
