In south Louisiana your vegetable is called Merliton. It is
not a root vegetable. It grows on a vine. It has a very high water content and a very mild flavor. It does absorb the flavor of anything it is cooked with. We make shrimp or crawfish casseroles with Merliton. It also makes a good quick pickle - serve with a salad. Good for a casserole with any flavorful protein.
Dad liked it boiled, salt and pepper and a drizzle of vinegar.
Experiment - think of it as a filler. It can also be stuffed with a savory mixture.
