Simple Vegan Split Pea Soup
You can use yellow or green split peas.
If the soup reduces too quickly before the peas are falling apart, add a 1/2 cup more water in Step 2. (And lower the heat under the pot.)
As the soup thickens again in Step 3, the risk of scorching can increase. Set the lid of the pot very slightly ajar to allow heat and steam to escape. Or reduce the flame to a poach (slower than a simmer: no bubbles, but active steam). Or place a heat diffuser under the pot. In any case, stir a little more often.
