Preheat a deep-fryer or heavy-bottomed pot, with enough canola oil to come halfway up the sides of the pot, to 375 degrees F.
In a medium-sized bowl, mix together the chives, jalapenos, shallots, garlic, white wine vinegar, and mustard. Season with salt and pepper, to taste. Set aside.
Season the pork with salt and pepper, to taste. In a medium-sized bowl, whisk the buttermilk and egg together. In a large bowl, combine the flour, paprika, cayenne, salt and pepper, to taste. Coat the pork on all sides in the buttermilk. Drain the pork from the buttermilk and add the chunks to the flour. Toss the pork in the flour insuring all of the pork is coated evenly. Shake off excess flour. Working in batches, deep-fry the nuggets until cooked through and crisp, about 3 to 4 minutes. Remove the pork from the fryer to a paper towel lined platter to drain. Transfer the pork to a serving platter and serve with jalapeno mustard.
