Stewness

Hello all!!! I'm about to enter the puree stage of my post op diet on Friday and was looking for some help/advice. In the liquid stage, I'm able to get down about 8-11 oz of liquid for my "meals" no problem. I have a feeling that will change when I switch to purées. Any suggestions how much food I should be eating per meal? Also, any suggestions for recipes and or shopping staples? I already stocked up on Greek yogurt but would love some suggestions on other staples. Plus I have only been able to find a handful of recipes online. Any help or suggestions are appreciated.
