Defrosted the peas by soaking in hot water a few minutes, then drain. The peas should be soft and cold. Do not microwave because the peas will turn grey and become shriveled.
Make the puree: Place all ingredients in a small food processor (3 cups) with the chopping blade. If making a single batch with 1 cup of peas, do not use a 14 cup food processor because there is not enough volume of food to touch the blade. Purée until almost smooth, but leave the texture slightly bumpy. Taste and adjust flavorings if needed. Cover and chill in the refrigerator.
Toast bread: Slice a baguette in ½ inch sections, and place cut side down on a rimmed baking sheet. Brush one side of each piece of bread with olive oil. Toast the bread in the broiler for about 1 to 2 minutes until lightly brown. Watch carefully, and do not walk away while broiling.
Assemble: Spread some pea purée on each piece of toast. Or serve the purée in a bowl, and let people spread their own. Serve lightly chilled.
