Soup:
2 pounds frozen green peas
4 tablespoons butter
2 (14.5-ounce) cans reduced sodium chicken or vegetable broth
2 medium onions, roughly chopped
Kosher salt and freshly ground black pepper
1/2 cup sour cream, for garnish
Bread:
1 demi-baguette (or 1/2 of 1 French baguette), cut into 8 (1/2-inch) thick slices
Extra-virgin olive oil
Kosher salt
In a medium pot, combine peas, butter, broth, and onions. If the peas are not submerged in liquid, add just enough water to cover them. Bring to a simmer over medium heat and cook for about 7 to 10 minutes, or until the onions are soft enough to puree and the peas are still bright green.
While the peas are cooking, grill the bread. Heat a grill pan over high heat for 3 minutes. Pour some olive oil onto a large plate. Sprinkle oil with salt then dip pieces of bread quickly on both sides into the oil. Grill bread until slightly charred and hot, about 3 minutes per side.
Using an immersion blender, standing blender*, or food processor, puree the soup until smooth and season with salt and freshly ground black pepper, to taste. Serve each bowl with a dollop of sour cream on top and grilled bread on the side.
