Drain and rinse the beans. Open the cans of black beans and black-eyed peas. Pour them into a colander and rinse under cold running water until the water runs clear. Shake off excess water and set aside to drain fully for a minute or two.
Make the dressing. In a small bowl or jar, whisk together the olive oil, fresh lime juice, red wine vinegar, honey, cumin, garlic powder, salt, and black pepper. Taste the dressing — it should be tangy, lightly savory, and just barely sweet. Adjust lime or salt if needed before adding to the dip.
Chop the vegetables. Dice the red bell pepper, red onion, and tomatoes into small, even pieces roughly the size of a bean. Slice the green onions thinly. Mince the jalapeño as finely as possible. Roughly chop the cilantro. Uniform, small pieces ensure every scoop has a bit of everything.
Mix everything together. Add the drained black beans, black-eyed peas, and corn to a large mixing bowl. Add the bell pepper, red onion, green onions, jalapeño, and cilantro. Pour the dressing over the top and toss gently until everything is evenly coated. Be gentle — you want the beans to stay whole.
Taste and adjust. Before adding the avocado, taste the mixture and adjust seasoning as needed. Add a pinch more salt, a squeeze of lime, or a touch more honey if the flavor needs balancing. The seasoning will shift slightly once the avocado goes in, so do not over-correct at this stage.
Fold in the avocado. Add the diced avocado last and fold it in gently with a large spoon or spatula. Adding it at the end prevents it from getting mashed during mixing. You want distinct, creamy pieces of avocado throughout the dip — not guacamole texture.
Chill before serving. Cover the bowl tightly with plastic wrap or a lid and refrigerate for at least 30 minutes before serving. This resting time lets the dressing soak into the beans and allows all the flavors to meld together. Serve with tortilla chips or use as a topping for tacos, grilled proteins, or rice bowls.
