My mom does bulgur wheat and it does a pretty good job at the texture. I prefer to do canned chickpeas run through a food processor just until roughly chopped, or use a potato masher. Readd the drained liquid after. Both work great, but I'd rather have more beans than wheat in my diet.
Every time I make chili it's a toss up for what recipe I use. Meat or no meat, chili powder or dried chilis. There are a lot of great ways to make it and it's hard to stay put.
Always oatmeal raisin. A lot of the other options you present seem too sweet without introducing any more complex flavors or new textures.
