For some, especially Southerners, it's tradition to eat collard greens, black-eyed peas, and pork on New Years Day. For those who may wonder why, here's a great answer.
All of the components symbolize good luck/prosperity/wealth.I'd suggest reading the other answers, too, at the above link.
The collards are green (and our dollar is still green, and the rest of the money is still mostly green) - prosperity.
The pork is symbolic of progress and prosperity because the pig is the only animal that eats while it is moving forward.
Black eyed peas symbolize good luck. There are several stories around as to why. [One story] is that when Savannah was burned to the ground, the people suffered great deprivation, and then, luckily, a huge barrel of black-eyed peas was discovered and the black-eyed peas kept the population from starving until more food could be had.
Have a happy, prosperous, and lucky year!
