Preheat oven to 425 degrees F. Slice off the top of the garlic bulb. Leaving bulb whole, remove loose outer layers. Place bulb, cut side up, in a ramekin. Drizzle with olive oil and cover with foil, roast until soft (about 10-15 minutes). Let cool.
Cook soybeans according to package. Drain and rinse with cold water. Squeeze 3-4 garlic cloves from bulb into food processor. Wrap and refrigerate remaining garlic for another use.
Add cooked soybeans, lemon juice, 1/4 cup water, 1/2 teaspoon salt, and lemon pepper to food processor. Cover and process until smooth. Transfer to bowl. Stir in parsley.
