Kid-Friendly Grilled Pork Tenderloin

1 . Stage

Mix sugar, garlic powder, salt, and red pepper flakes together in a bowl. Rub mixture over all sides of pork tenderloin. Let sit at room temperature for about 30 minutes before grilling.

2 . Stage

Preheat an outdoor grill for low heat and lightly oil the grate.

3 . Stage

Place pork on the grill and cook low and slow, turning every 10 minutes, until all sides have been cooked, about 30 minutes. Brush with barbecue sauce and repeat every 10 minutes, for about 30 minutes more. Pork is ready when slightly pink in the center and an instant-read thermometer inserted into the center reads at least 145 degrees F (63 degrees C), about 1 hour total cooking time.

4 . Stage

Remove pork from grill and let sit an additional 5 minutes.
