Preheat oven to 400 degrees F, and grease a baking sheet
Peel off the outer layer of the garlic head and cut off the top to expose a bit of the garlic cloves.
Place on a baking sheet and drizzle with 2 tsp of olive oil.
Place the bell peppers next to the garlic, cut side down.
Roast for 30 minutes until the garlic is tender and the bell peppers are charred on the outside.
Remove from the oven, and place the bell peppers in a bowl and cover with a plate so they can steam for 5 minutes.
Peel and discard the skin of the bell peppers.
Squeeze out the softened garlic cloves in to a blender, along with bell peppers, 2 tbsp olive oil, and the rest of the ingredients.
Blend until smooth and creamy.
Taste to adjust seasoning, and enjoy!
