One low carb snack is to bake squares of cheese on parchment paper.
I’ve used cheddar and american but my favorite is fresh shredded parmesan. It doesn’t keep well though so just do what you will eat right away.
I also make mini pizza snacks of a slice of pepperoni with pizza sauce and mozzarella on top. You can heat them in the microwave or oven and they are really good. A little messy though ;)
I just buy a slice of pizza with the works. Give the crust to my girls and eat the topping. Lots of mozzarella, meats and veggies. No more pizza craving
