I used to own an instant pot. Those are great. I gave it away when I moved and now I just have a regular pressure cooker, which is also really great.
My quickest and easiest, but still yummy thing to make is chickpeas. I soak them overnight. Pick out the ugly ones. Drain the water. Barely cover them with fresh water (since they’ve already soaked, they don’t need tons of water). Then I heat the pot on high until I hear the pressure noise, switch it to low heat, and let it cook for 15-20 minutes. Then I turn off the heat and let the pressure out naturally.
Once they’re done I sometimes just eat a bowl of them with nothing more than olive oil and salt. Yum.
One of my other favorite dishes is a bit more elaborate but still simple and healthy: split pea soup. I don’t soak the peas but I do rinse them. I put them in the pressure cooker with a bay leaf, chopped garlic and onions, diced potatoes and carrots, and I’ll cover the whole thing with a decent amount of water. Then, like the chick peas, I’ll let the pressure hiss, then put it on low heat for 15-20 minutes. I let the pressure naturally release.
Sometimes I’ll sautée even more onions and garlic in a separate pan with avocado oil on low heat for a while, until they look like they’re getting caramelized (fucking yum).
When the soup is done, I’ll remove the bay leaf, add the extra onions and garlic (if I did that step), add some salt, then use an immersion blender. It’s SUPER IMPORTANT to remove the bay leaf if you use an immersion blender.
Then when I eat it, I put a decent amount of olive oil and make sure the salt level is tasty. Even better if I have spicy olive oil around :)
someone mentioned rice and beans but im going to specifically say rice and lentils. dry lentils will cook up with rice in a rice cooker along with the rice with no extra steps. just rinse the rice and dry lentils (or don’t but uh, modern food can have some nasty chemicals) put in the cooker with the usual two cups of water for each cup of solids. Add anything handy you can for flavor be it seasoning or veg or sauces or whatever. Literally cannot think of a simpler meal to make and its ingredients don’t need canning or refrigeration necessarily. Just need the rice cooker for convenience.
