keto/low carb freezer prep

Hi folks! So I have a friend who will be going into surgery soon, and one thing I was looking for is some keto/low carb freezer friendly meals that can just be heated up so she doesn't have to really cook. I personally am not on a keto diet, but my friend prefers the keto lifestyle as it keeps some of her stats in check.

I've seen several recipes for egg cups/quiches, which I can make. She also has a sous vide, so I will prep some protein in vacuum sealed bags, it will just leave her with searing it up once its out of the water.

I'm looking for recipes that serve 2-6, as it will just be her and possibly her boyfriend. Or recipes that I can portion into individual servings. I do not believe she will be sticking to low calorie, so I'm not so worried about calorie count per se. I've been browsing pinterest, but a lot of the make-ahead recipes I'm finding are more like "prep/chop/clean all the foods for the week and assemble when ready" rather than "put it all together in one bag/container, freeze, then heat when ready".

Does anyone have any go to recipes, or recipes they've adapted to the make ahead/freezer method? Thank you for any help!
