Just take any meal you eat and put it in a blender and puree it. I had a memorable Thanksgiving meal where I just mashed together some turkey, a little gravy mix powder, a splash of milk, some instant potato flakes and topped it with a spoonful of cranberry sauce. You didn't say what food stage you're at, but if your nutritionist told you to puree, I'm assuming you're at the soft or solid food stage.
We have a recipes forum in this group, though I haven't found it...
