Just in case the point above gets lost, avoid straws. The suction can dislodge the blood clot over the extraction, which often leads to dry socket. Trust me; it's very unpleasant.

I ate spaghettios, if you don't mind the taste, or even like it.

Steamed egg in chicken broth, like what they serve in Japanese restaurants.

Baby food slides right down, and the fruit varieties are pretty darn tasty.

oatmeal - puddings - pasta - ice cream - rice - yogurt - baked beans

By day three I was able to manage macaroni and cheese and pancakes (lots of butter and syrup and mashing with my tongue, YMMV on that)

lightly fried eggs with mashed potatoes

Campbell's Soup at Hands are awesome, too. I recommend the Creamy Tomato, the Potato and the Creamy Chicken 

Carnation Instant Breakfast- 'You're gonna love it in an instant'

all stuff-in-a-blender is okay -- fruit smoothies, I remember hot dogs worked pretty well, chicken not so much (actually, chicken worked all right, barely, but looked like cat food), fish. Vegetables, like beets and cooked carrots, tend to work well in a blender.

Farina (aka Cream of Wheat). Made from scratch with milk it's high in iron and generally equivalent to breakfast cereal. Put in some real maple syrup at serving time
