The "Fast Money" traders explored trades in the consumer spaces of fast food and retail on Tuesday.

Trader Pete Najarian said when he looks at the fast food space, and especially the pizza area, he doesn't know why Papa John's doesn't get as much attention as Domino's. Papa John's finished the day up 1.8 percent. The company's stock is up nearly 10 percent this quarter and up more than 50 percent this year.
