What rhearob said.
I will tell you that personally I was having liquids only (protein shakes/water/jello****il 3 weeks out.
I then moved into things like greek yogurt, cottage cheese, pureed soups.
Then finally at around 6-8 weeks was I able to eat the things you are talking about.....soft fish, scrambled eggs, cooked veggies.
I have not touched anything like oatmeal or mashed potatoes since surgery.
This was my plan. Your surgeon and nutritionist have designed one for you. Don't push boundaries this soon. You might regret it.
