I don't follow keto, but I've found a number of good low-carb recipes by searching online. They do a pizza crust that's made of almond flour and mozzarella.
I get the low carb or carb-zero tortillas from the grocery store. They also sell cheese wraps in the dairy case. If you like to bake, sourdough is a good option because the fermentation process removes some of the sugar from the bread.
Turn sandwiches into salads. I've done burger bowls, with all the meat, cheese, veggies, and condiments you would eat on a burger, but in a salad instead of on bread. Lettuce wraps are just weird and messy for me, but a lot of people like them. I've heard raw collard greens make a great wrap but I haven't tried that yet.
