Hi Amy,
Since the surgery, I have found that I like to have easy meals ready to grab. I do enjoy cooking, though, too.
For breakfast, I often have a protein shake or yogurt with protein (oikos triple zero or light & fit). Sometimes, I may have oatmeal (can add protein powder, there are some brand that have it added), frozen lower carb or keto waffles with protein & sugar-free syrup, or low carb/keto bread with cheese or egg. You can find cooked hard boiled eggs in dairy section. There are also those "just crack an egg" microwave meals (I haven't tried them).
For easy lunches I often have yogurt, Oscar Mayer P3 snacks or Sargento Balanced breaks, 1/2 sandwich with low carb bread turkey & low fat cheese. (I don't know if you are ready to eat nuts, yet, I know they need to be chewed well & controlled portion sizes)
An easy dinner I found was a frozen pizza made with a chicken based crust. There are some frozen keto meals i have seen, but haven't tried. Other easy items are: frozen cooked shrimp, cooked grilled chicken from supermarkets deli, & microwave riced cauliflower.
I hope you get some ideas. I am always looking for new foods to incorporate into my routine, too.
