Melt the mozzarella in the microwave (ca 90 sec-2 min). Alternatively, heat gently in a non-stick pot.
Add the almond flour/ground almonds and psyllium husk plus the salt and spices, if using. Stir until combined, then knead until you have a smooth dough.
Separate the dough into 2 balls and roll out between 2 sheets of baking/parchment paper. Roll out as thinly as possible! The thinner, the crispier your tortilla chips will turn out.
Cut into triangles (I used a pizza cutter) and spread out on a sheet of baking paper so the tortilla chips don't touch.
Bake 6-8 minutes or until browned on the edges. Baking time will depend on the thickness of your tortilla chips. I baked mine in 2 rounds, plus a third round for the off-cuts.
My tortilla chips weighed around 5-8 grams each and the batch made around 40 chips. I'd say if you have a couple of dips, they would be enough for 8 people as a nibble/appetizer (or 4 people if it's more the main attraction of the evening). 1.9g net carbs per portion. Nutrition is calculated on the basis of 8 servings (5 tortilla chips per serving). If you don't have psyllium husk, use 2 more tbsp of almond flour instead. UPDATE >> A reader who made these pre-cut the tortilla chips, but did not separate them by hand. They separated on their own whilst in the oven. I have not tried this myself yet, but will do when I make my next batch!
