Burrito recipe to be frozen?

I found a burrito recipe that says they can be frozen individually. I want to make it because my hubby is a fan of those burritos you can buy in the freezer section and I know I can make them better, healthier and cheaper. :) The question is, the recipe has no meat and I wonder if I can add ground beef or chicken and still freeze them the same? (Hubby is a carnivore lol!) Has anyone made burritos to freeze? Did you use meat? Any advice welcome.
