Add the peas to a large pot, along with three cups of water. Bring to a boil, reduce to simmer for 5 minutes, then drain and return the peas to the pot.
4 cups frozen peas, 3 1/2 cups water
Add the milk, salt, butter, and pepper to the pot and stir everything together to combine. Bring the mixture to a boil.
3 cups milk, 1/2 tsp seasoned salt, 1/8 tsp freshly cracked black pepper, 1 stick butter
As soon as the milk begins to boil, separate and drop the biscuits into the pot. Let the milk bubble up over the biscuits, but NOT over the edges of the pot.
1 16.3 oz can refrigerated homestyle biscuits
Reduce the heat to a simmer, and continue cooking for 2-3 minutes. Carefully flip the biscuits, and simmer another 2-3 minutes- or until the biscuits are no longer 'sticky', and look just a little tough.
Serve warm with the pea gravy spooned over the biscuit dumplings.
