Whisk together vegetable oil, lime juice, and Sriracha sauce and pour into a gallon-sized plastic bag.
Cut the chicken into 1 inch cubes and add it to the bag. Once all of the chicken pieces are in the bag, turn the bag to coat the chicken with the marinade and place in the fridge for about 1 hour, turning after half an hour.
Preheat the oven to 350˚F. Take 1 pound of bacon and cut each slice into three pieces. Wrap the bacon around the chicken pieces and secure with a wooden toothpick.
Coat the bacon wrapped chicken in brown sugar and place on a greased broiler rack and pan. For extra heat, brush bacon with Sriracha before coating it with brown sugar.
Bake at 350˚F for 30-35 minutes. Then, open the oven door slightly and broil the bacon chicken bites until the bacon is crispy, turning the chicken every couple of minutes to prevent burning. Be sure to watch carefully because ovens vary, and food can burn quickly while broiling.
