For the peri peri marinade, combine olive oil, red wine vinegar, lemon juice, hot sauce, honey, ginger, garlic, onion powder, black pepper, salt, paprika, and oregano in a blender jar. Blend until the marinade is smooth.
Place chicken thighs in a large bowl and pour in the marinade. Scrape the blender jar with a silicone spatula to get all the marinade.
Marinate the chicken for 8 hours to overnight. If you're really short on time, try for 30 minutes at least.
Preheat grill to medium-high temperature (400 degrees Fahrenheit or 205 degrees Celsius).
Remove chicken from marinade using tongs or a slotted spoon and discard marinade.
Grill chicken thighs until internal temperature reads 170 degrees Fahrenheit, flipping the chicken every 5 minutes, for a total of about 20 minutes.
