"This is an adaptation of several bean recipes from different sources. It is best after leaving overnight for the flavors to meld. Serve at room temperature."
1Pour the corn into a microwave-safe dish; cook in the microwave until heated through, 2 to 3 minutes. Drain any excess liquid, and set aside to cool completely.
2Blend the cider vinegar, lime juice, garlic, cumin, Dijon mustard, black pepper, salt, olive oil, and cilantro together in a blender until combined.
3Toss the cooled corn with the black beans, butter beans, red onion, and red bell pepper in a large bowl; pour the blended dressing over the bean mixture. Refrigerate overnight; allow to come to room temperature before serving.
