Place peas in a sauce pan with about a half inch of water on the bottom.
Bring to a boil and then cover and reduce heat to medium. Cook for about 5 minutes.
While that is cooking chop up your onion and mint.
When your 5 minutes is up drain the peas in a colander and then return the pan back to the burner with the heat on low. Add your butter and then pour the peas back in and stir around until your butter is all melted. Turn off the heat when the butter is all melted.
Add your onion, mint, and garlic.
Finally add a little salt to taste and stir it all up!
