In a skillet, heat the oil. Add the pork mixture and cook over high heat, stirring to break up the meat, until no pink remains, 5 minutes. Remove from the heat and stir in the lime juice mixture. Let stand for 5 minutes. Transfer the meat to a bowl; stir in the herbs. Season with salt and pepper. Top with the peanuts and sliced jalapenos.
