Other eternals

1. Canned tuna. Be as fussy or unfussy as you like.
2. Other canned fish/seafood (same deal).
3. Pasta - there are no rules.
4. Rice - there are some rules, but start by just buying something basic. I recommend a decent basmati, and will provide the recipe that gave me the confidence to start making rice.
5. Canned AND dried beans. See what works for you. I keep both on hand.
