Rinse the jalapenos with water and slice them lengthwise to make two portions. Scoop out the seeds. Allow to dry and reserve.
Add olive oil onto a hot frying pan. Sear the ground beef. Pepper and salt the meat to taste. When the meat is brown and cooked, transfer to a dish and set aside.
Stuff the inside of the half jalapeno pieces with a small teaspoonful of cream cheese. Evenly spread to cover the interior.
Top the cheese-stuffed jalapenos with a scant tablespoonful of the cooked ground beef.
Wrap a half bacon slice around the jalapenos.
Arranged all the jalapenos neatly on a baking sheet. Leave in the preheated oven (set at 375°F) for 15 minutes. Crisp and brown the bacon before removing from the oven. Transfer to a serving dish with sour cream sauce on the side. Best eaten warm.
