For a couple of quinoa recipes, check out the blog "101cookbooks" by Heidi Swanson. "Heather's quinoa" is easy and tasty, and could last a few days in the fridge if divided up into smaller portions. I've never bothered with roasting the tomatoes, but I'm sure that would be tasty. The "Double Broccoli quinoa" is great, too - but it might not be great for you depending on how broccoli affects you gassy-wise : ) You could skip the cream in the recipe or use silken tofu to make the pesto creamier.

She also has a recipe in her book "super natural everyday" for quinoa patties, if you can find it at a library. I found them a little bland (sounds like that would be good for you), but pretty tasty and easy to keep a bunch in the fridge for snacking. Seems like you could easily add in flavors that you like to make it suit your preferences.

Consider trying tempeh instead of tofu if you are looking for a non-meat protein. I find it easier to cook with because it stays firm and has a chewier texture, you can use it anywhere you'd use meat. I use it in burritos, chili, stir fry, everything when I want a protein blast. Again, you have to consider how this (and tofu, actually) would affect you, gassy-wise.

Best wishes and a speedy recovery to you.
