So be careful with qasadillas. The onions and green peppers have higher carbs than leafy greens. That combined with the tortilla, even a low carb tortilla can add up.
When you do them, be sure to buy block cheese and shred yourself as pre-shredded cheese will typically contain corn starches to keep it from clumping. Thus adding even more carbs.
And if you use sour cream or guacamole, there are additional carbs. Though these items are perfectly okay Keto wise (at least if the guacamole is homemade) the incidental carbs they contain added to those of the veggies and tortilla can again add up.
This meal could quickly spiral out of carb limits.
Especially if you have more than one.
I don’t mean to scare you completely. If done carefully with moderation, you can certainly do it. But it’s one of those things that’s very easy to get wrong.
I second the suggestion to use chicken thigh instead of breast meat. This will up your fat content.
I would also try for zero carb meals the rest of the day when you have these just to make sure you don’t go over your daily count.
