Warm the beans and minced garlic with a couple of tablespoons of water. You can do this in your smallest sauce pan on the stove over medium-low heat (sauté the garlic in a drizzle of olive oil before adding the beans) or in a bowl in the microwave. Add little splashes of water as necessary. Use a fork to mash up the beans a little and add salt to taste, if necessary.
In a bowl, combine the kale, cilantro, jalapeño, lime juice, olive oil, cumin, chili powder and sea salt. Mix well and set the bowl aside to marinate.
