If you have dried peas, soak ¼ cup of these overnight in water. Later drain the water and rinse them a couple of times. Pressure cook the soaked peas in 1½ to 2 cups of water in a stove-top pressure cooker for 18 to 20 minutes or in your Instant pot for 15 to 20 minutes. The peas should be softened but not mushy or pasty. Drain and then use the cooked dried peas replacing fresh green peas as listed in the recipe.
