This can be a tough diet to follow - at least, if you're like me and have always preferred high fibre / whole-grain everything, along with preferring raw or just barely warmed vegetables!
There are a few good resources on-line for low-residue diets (try MD Anderson, Mayo Clinic, and WebMD). These will give you the basics as to the types of food you can have and the types to avoid. I haven't run across any recipe sites for this, but did find that almost anything I liked before this could be adapted by ridiculously overcooking the vegetables (and quite often pureeing them) and changing out my beloved whole grain for white flour pastas and breads.
When I was on this for 1-1/2 years, my mainstay dinner (at least a couple of nights per week) was white pasta with tomato sauce. You can have fruits and vegetables as long as they are well cooked and do not include skins or seeds, so I would steam onions, carrots, broccoli, cauliflower, and other vegetables first, then puree them and add them to the sauce. Along with some garlic and spices, this gave me great flavour and lots of nutrients, while staying in the diet guidelines. I would also sometimes mix spaghetti squash in with the pasta (also well cooked prior).
Meats are within the guidelines, but try to make sure that either they are very moist, or that you add a source of moisture while eating them. I made a lot of soups, with the meat and vegetables cooking in the liquid for a long time. Cream soups (using greek yogurt for the "cream") were really good for added protein.
I also tended to always make a gravy for any meat that I was eating as "stand alone" --- I made these with low sodium broth (chicken broth for poultry / beef broth for beef and pork), spices, sauteed and pureed onions and garlic, and thickened with corn starch or white flour. So I could have, for example, baked chicken with a side of mashed potatoes/cauliflower, with gravy over both, preceded by a cup of soup.
I'm not a huge white bread fan, but do enjoy a really good french bread. I used this for toast (spread with a nut butter and / or a fruit jelly that had no seeds or skins), as a side with soup, or for sandwiches (usually tuna/salmon/chicken salad with a lot of dressing).
I went with the candy kids' cereals for breakfast --- these were the only ones that are low in fibre but are enriched with lots of B-vitamins and iron. Corn Pops were the ones that worked the best for me.
Although I didn't go this route, I know a lot of people who love juicing while on this diet. That way they get all the nutrients of the fruits and vegetables without any of the seeds and fibre. I tended to do the puree of cooked veggies and adding it to everything instead.
Every body is different, so you will end up having to experiment to see what tastes good to you, and what works well with your tummy and your medical circumstances. I was on this diet while I was on chemo, so had some other nausea issues to contend with at the same time. I couldn't stand either Ensure or Glucerna, but found that Carnation Instant Breakfast was sometimes tolerable. Ice cream and arrowroot cookies were always tolerable (hence why I'm on this site now!), and for me, they always eased the nausea.
Good luck, and I hope your health problem is easily and happily resolved soon!
