Snack Ideas & Rice Cooker for More than Rice

Here are some snack ideas that work for me:

If you have a Rice Cooker you may want to try cooking the following foods in there. I'm still experimenting myself. You may use broth for the liquid. Let me know if these proportions work for you. I'll adjust/edit here as I try this myself. I always burn this kind of stuff when cooking on a burner, so the rice cooker is preferable.

Quinoa
1 part quinoa, rinsed
2 parts liquid

Steel Cut Oats
1 part steel cut oats
3 parts liquid

Lentils
1 cup lentils, rinsed
2 cups water

Pearl Barley
1 cup barley
2 cups water

I'm working with a small rice cooker like the one below, so it's not really fancy. I want to try beans, split peas (especially yellow split peas, because they're a true superfood).

Again, if you've ever tried a variety of different legumes, grains, or the like in a small rice cooker like this, please tell me how it worked out for you.
