Cook Lima beans for 30-40 minutes until tender.
First bring water to boil and then cook on medium high flame.
Allow lima beans to cool and discard water.
Take 1 ½ cups water, soaked beans, ¼ tsp Salt, ½ tsp oil (opt) in instant pot inner vessel.
Cook on heigh pressure; pressure cook or manual option, for 6 minutes and natural pressure release.
Peeling the skin of the beans is optional but I highly recommend.
Skip this step for beans cooked in Instant pot, as it could be a challenge.
Take beans between fingers and press. Beans will pop out.
If it does not, using other hand, pinch the bean to tear the skin and then press.
Add onions and tomatoes and toss. Add Lima beans, toss and sprinkle cilantro or parsley.
