I am moving into pureed consistency foods this weekend. Tofu is a good source of protein. The silky tofu can be added to shakes. The firm and extra firm can be marinated, pan seared, among other ways of cooking. I will be using tofu, tuna, homemade chicken (soaked in buttermilk at least overnight to keep it very tender), refried beans and unflavored protein powder for my protein sources. I will try eggs a few different ways (poached seems to have the highest success rate among sleevers) and hope I can tolerate them.
I'll also be using Greek yogurt, applesauce (with the protein powder, and cottage cheese.
I plan to make a sandwich paste (like chicken or tuna salad but pureed) and include flavor from onions, pickles, etc. I plan to use salsa with cooking as well for some added flavor. Maybe some plain Greek yogurt for some flavor and protein too.
