Place refried black beans in a microwave safe dish, cover and heat in microwave until warm (about 1 minute).
In a separate bowl combine onion, tomatoes, cilantro, lime juice and mix. Add salt to taste.
Assemble your dip in desired container (casserole dish, or individual parfait cups) by placing the black beans down first and use the back of a spoon to flatten out evenly. Top with diced avocado, then the onion and tomato mixture, jarred jalapenos, and finally sprinkle with the queso fresco cheese.
