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 :)
Tomato pasta.
Boil a pot of water, and add your pasta. In a separate pan/pot, throw some cherry tomatoes in with some olive oil and cook on a medium/high temp. The skin will char, and it breaks down the juice will come out. Add some.garlic (sliced, crushed, whatever suits), and after 30 seconds throw a splash of red wine in with a stock cube and let it reduce to a jammy consistency. As things get dry, add some of the pasta water to keep things jammy. Once the pasta is a minute from being done, throw it in with the sauce and cook until everything is done. Add some basil at this point if you want, and maybe some chilli. Lunch is done in 10 mins.
Another fave is Tomato and Pepper Soup. Cut some big tomatoes, an onion, and a pepper (equal numbers of these), along with some garlic cloves in their skins, and put in a ceramic container to go into the oven for 30-45 mins. Once done, blitz in/with a blender until smooth (make sure the garlic is out of the skins first), add some stock, and finish with some cream, and you're done. It's much slower, but takes maybe 5 mins of effort.
