I use my rice cooker a lot. I cook my grains like savory rolled grains for breakfast or lunch. This is a mix or rye, spelt, hulled millet and buckwheat groats that I make myself and then I add nutritional yeast, cumin, chili powder, and various other spices, then I cook in my rice cooker. I use my rice cooker to steam veggies as well. I rarely eat any "manufactured" food even veg*n. On occasion I do have a veggie patty or veggie dog. My food is all grains, seeds, roots, leaves, fruit etc. No oil, no sugar -- maybe a bit of white flour in bread because I still buy bread. To sweeten, I use stevia. Not sure how safe this is. I try to get high grain bread, but sometimes I fall a bit short. Sometimes I will eat canned foods, but they can only contain 2 ingredients -- that item and water. Since I am still transitioning to vegan food, I was having some problems giving up cheese and eggs. Now, I think I have kicked the habit.
I do not have a sweet tooth-- thank the elements-- I have a crunchy/grease/salty tooth and so getting away from crunchy dry salty snack food has been a problem. I see that I can air pop pop corn, and put nutritional yeast on it, making a good snack. Salad dressings are also a problem. I love salad, and formerly loved putting massive amounts of cheesy dressing on it. I've been using balsamic vinegar, and it is not doing it for me. Maybe I will get used to this.
I also eat a lot of cruciforms, like cabbage and cauliflower. A typical meal for me (what I ate last night) would be steamed sweet potatoes and cauliflower with a side of spicy quinoa pilaf, and an avacado/onion/tomato salad, and a few tangerines for dessert.
