In the southern United States, eating Hoppin' John on New Year's Day is thought to bring a prosperous year filled with luck. The peas are symbolic of pennies or coins, and a coin is sometimes added to the pot or left under the dinner bowls. Collard greens, mustard greens, turnip greens, chard, kale, cabbage etc. along with this dish are supposed to also add to the wealth since they are the color of money.
I had leftover ham and a bag of black eyed peas. Combined recipe on bag with Betty Crocker and tweaked a bit.
