Bring pot of 4-5 cups of water to a boil.
Drop in the potatoes and boil for about 20 minutes. Set timer for 15 minutes.
In a smaller pot or pan, add the olive oil and cook on medium heat. Add the garlic, collard greens, paprika, and salt to taste; sauté for about 5 minutes. Add the corn and continue to cook on low-medium heat for another 4-5 minutes.
At 15 minutes (when your timer goes off), add the peas to the potatoes to boil.
When the potatoes and peas are done, drain off most of the water (leaving about 1⁄2 cup behind) and mash them with a potato masher or large spoon until smooth.
Stir the greens, garlic, corn, and sage into the potato-pea mash.
Salt to taste and enjoy.
