.....but, just FYI. Chickpea flour is hardly Keto, not at 53 grams of carbs per cup, or 106 carbs for two cups. If you get 10 tortillas out of the recipe, that's nearly half your carb allotment for the entire day. Keto is low-carb, but high fat. With the emphasis on healthy fats, like butter, lard, coconut oil, etc.
Ditto for refried beans--beans in general, are way too carby for Keto. But, if they fit into your daily macros, then by all means, go for it. However, most people on Keto have enough weight to lose that beans are off limits for a long time.
As for the tortillas, I mix up ground chicken breast, or thighs, which has more fat and flavor. Add parmesan cheese, mozzarella, an egg, and seasonings of choice, such as garlic, dried cilantro, chipotle, etc. Form into a dough, divide into about 6-8 balls, depending on size you wish. Put each one through a tortilla press, and cook in skillet. Just enough to set, you don't want to cook them all the way through.
Cool, wrap and freeze. They're very versatile, and much easier to work with than conventional flour tortillas. They don't tear, and you can roll them without heating first. Just defrost if coming from the freezer. And the carb count, being mostly cheese and chicken, is pretty much zero. Win/win! I've lost over 40 pounds eating this way, and I love it!
