Having been on a soft food diet now for about 6 months I have learned to become quite inventive with the blender...I've basically been eating lots of yoghurt, ice cream, apple sauce, soft cheeses, hot cereal, hummus, lightly blended stirfried veggies and salmon/fish (salmon lightly done so it's still very soft and then you don't have to blend it), blended lasagna, mexican refried beans with guacamole, salsa,sour cream, indian dhal or soft/pureed indian or thai curries, black bean soup with melted cheese, nut butters, smoothies (add protein powder). Often I'll just take a regular dinner and blend it. You can blend stirfried veggies very lightly until they are just little bits rather than a mushy puree and it tastes quite good. I take lasagna and put it in a freezer bag and mush it by squishing the outside of the bag. This softens it enough so that I don't have to chew it but leaves enough of the natural textures that it still resembles lasagna. It may sound weird but you get desperate for decent food after a while!
Hope this gives you some ideas! Good luck
