It depends on your plan post-op. Each plan is different. Mine was full liquids (yogurts, soups, shakes) the two weeks, then purees, then soft foods, then full meals all at 2 week intervals. So by 8 weeks out I was eating "normal" food. I have two teen daughters and a husband and I am a planner too. Generally before shopping each week I plan the protein for each night so I'm not scrambling with the what to cook or make with this issue when I get home. I just kept up my normal routine for them. During my first 2 weeks, I ate lots of greek yogurt and soup. Sometimes the eggface ricotta bake. I fed my family the usual stuff we would eat. In purees, if I made them meatloaf, I'd just mash mine up more - same with chili. By the third phase - it was lots of chicken and fish.
For work, I don't have access to a fridge, so I pretty much pack the same thing on my office days. (I work from home a few days a week.) Chicken salad, romaine lettuce, yogurt and a cheese snack. Sometimes an apple (but I'm 1+ year out.) I didn't freeze stuff before surgery and I'm glad I didn't - my taste buds were off for a few weeks after surgery.
