Every night I have a base of either quinoa or rice, prepared in my rice cooker with various vegetables and spices. If rice, I'll roll it up with nori for homemade veggie rolls.
With dinner I have a 12 ounce glass of water with two tablespoons of flax and one tablespoon of chia.
I buy my pinto beans and black beans loose in bulk at the local grocery store when picking up my vegetables, usually around 5 or 6 pounds of each at a time.
Cumin, garlic powder, tahini, and dry garbanzo beans go for a good homemade hummus in a food processor. Needs a fresh lemon or two squeezed into the tahini. Original recipe had olive oil and salt, I leave out the oil entirely and either cut the salt down to a dash or none at all.
I keep oats and almond meal on hand to make pdb cookies with the same food processor, just add a banana or two, cinnamon, nutmeg, almond butter, and raisins if you like. The original recipe called for dates and I said eat me I'm doing raisins.
I got peppermint in bulk to make tea with, both by itself as well as mixing with chamomile, mugwort, etc.
I keep almost all of the above in these convenient cereal containers to both extend shelf life, shelf space, and remove any branding or advertising. Mason jars are also awesome!
Don't forget you can dehydrate your own food as well!
Edit: I don't work for Amazon, I just live no-car and order like this to survive!
