1. Combine the black beans, corn and tomatoes in a medium bowl.
2. Add the Marcum spices and diced onion, then stir until evenly combined. Taste, then add salt if needed. Refrigerate until ready to serve.
This Black Bean & Corn Salsa goes great with Senora Verde White Corn Chips!
If possible, make ahead of time (a day or so in advance) for even more flavor.
