Heat skillet over medium heat. Add the chopped bacon and stir occasionally until bacon is crisp. Using a slotted spoon, remove the cooked bacon to a paper towel lined plate. Set cooked bacon aside.
Add the chopped onion to the bacon grease in the skillet. Cook for a few minutes until the onion is starting to soften.
Add the ground sirloin and cook until no longer pink, breaking up the beef with a wooden spoon or spatula.
Add the corn, Zatarain's Black Beans and Rice Mix and the water to the skillet with the cooked onion and ground sirloin.
Bring the water to a boil. Reduce heat so the skillet contents are gently simmering. Put the lid on the skillet and cook for 25 minutes, or until rice is tender.
While the rice mixture is cooking, turn the oven to the broil setting.
When rice is cooked, remove the lid from the skillet and top the cowboy rice skillet with the shredded cheese.
Put the skillet under the broiler for a couple of minutes to melt the cheese.
Top the skillet with the cooked bacon, sour cream and pickled jalapeños and serve immediately.
