Heat 2 tbsp of the olive oil in a skillet over medium heat. Once hot, add the garlic cloves and diced onions and sauté for 4-5 until softened.
Add the frozen peas, and cook until softened and easily smushed with a fork.
Add the pea mixture to a food processor or blender, and while mixer is running, add the remaining 2 tbsp of olive oil. Process until a thick paste forms.
Taste for seasoning and adjust. Spread on toast of choice and enjoy!
