My program skipped pureed foods and went directly to soft proteins with the instructions to chew thoroughly. But your best bet for purees is blended soups. You can make a very flavorful soup and puree it, and it will still be tasty (as opposed to pureeing meat, which is gross). Bean soups and butternut squash bisque work well. You might also try a ricotta bake in that stage, which can be made by mixing a cup of ricotta and an egg, spreading this in a greased baking pan, and topping with a non-chunky marinara and some mozzarella and parmesan, and then baking at 350F until the cheese is nice and brown, maybe 30-45 minutes.
As for protein drinks, you should plan to be supplementing with those for quite some time, at least several weeks. Some people can get what they need from food really early, but others need at least one protein shake a day for several months. You also might want some plain, unflavored protein powder to add to things like soup or smoothies to increase protein.
