This is one of those recipes that you just can't walk away from at the summer potluck. My sister's MIL makes it and I beg her for it every chance I get! Apparently it is a family recipe in her hubby's family, though I can't say I know who Mabel was. Regardless, I owe thanks to Mabel for a darn fine salad that is bright, refreshing, and COMPLETELY addictive! Number of servings is my best guess, and prep time does not include overnight refrigeration.
