I'm having trouble with this myself. Eggs are great, also tuna mayonnaise made with light Hellman's. I have dairylea triangles for quick protein fix, they were perfect especially when I was transitioning off liquids because they kinda melt in your mouth. I've started having avocado, because of the protein and also it's a healthy fat. I just wasn't able to cope on 800 calories and so avocado is great becuase yeah it's high cal but it's soft and easy to digest and at this point I need the calories. I can't tolerate meat. I've tried twice, first with beef mince in tomato sauce and then chicken but both times I ended up in pain even though I chewed it half to death. BAD pain. I'm 5 weeks post op and a typical day will be redy brek made with soymilk and non sugar sweetner, or maybe a protein shake. Lunch can be tuna or egg mayonnaise, or half an avocado with low fat hummus. Dinner, probably soup and maybe some water biscuits. I need to start eating fresh fruit and veg but I'm scared of it getting stuck. Good luck! Shellbell's link is a great help.
On days when I need an early start and not hungry, I'll have a banana cut into slices and spread with peanut butter. Again, high calories but it keeps me going.
