Mix the black beans, corn, tomatoes, bell pepper, cilantro, lime juice, olive oil, and salt. Stir gently until everything is coated. Place the bowl in the refrigerator while making the cheese mixture.

Add softened cream cheese into a large bowl. Stir until smooth. Add sour cream, garlic powder, onion powder, paprika, salt, and black pepper. Mix well until creamy and fluffy.

Mix in the shredded cheddar cheese and pepper jack cheese. Stir until every bite has plenty of cheese. Fold everything together gently without overmixing the mixture.

Add chopped jalapenos and sliced green onions. Mix gently until evenly spread throughout the cheese mixture. Taste and adjust the seasoning if needed before shaping.

Lay plastic wrap on the counter. Spoon the cheese mixture onto the center. Roll tightly into a log shape. Twist both ends closed and smooth the surface.

Place the wrapped cheese log into the refrigerator. Chill for at least one hour. This helps the log become firm and keeps its beautiful shape.

Remove the plastic wrap carefully. Spoon the prepared cowboy caviar over the cheese log. Press lightly so the vegetables stick well without breaking the shape.

Place the cheese log on a serving plate. Arrange crackers, tortilla chips, pretzels, and vegetables around it. Serve immediately while everything is fresh and colorful.
