Step 1 In a medium saucepan, gently boil the peas in the 1 quart water until tender, about 30 minutes. Season with one-half teaspoon salt near the end of the cooking time. Strain and set aside.
Step 2 In a large bowl, mix together the tomato, cucumber, bell pepper, green onions, parsley, lime juice, habanero, remaining one-half teaspoon salt and one-eighth teaspoon pepper, or to taste. Gradually pour in the oil while whisking the mixture together. Gently fold in the black-eyed peas. Cover and allow to sit for 1 hour so that the flavors can marry. Serve in the lettuce leaves.
