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. [See Note 1]
Grill Instructions
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.
Instant Pot Instructions
Add water to the Instant Pot. Transfer chicken and marinade to the Instant Pot. Be sure to scrape the bowl with a silicone spatula to get all the marinade into the inner pot.
Pressure cook for 9 minutes on High Pressure.
Do a natural release of pressure (QR). If short on time, you can do a 10 or 15 minute natural release. [Read More: The Different Pressure Release Methods]
Using a slotted spoon or tongs, transfer chicken from Instant Pot to a large plate or bowl.
In Saute mode, heat the sauce until reduced and thickened, about 10 to 15 minutes.
Let the chicken thighs rest while you prepare your grill. [See Note 2]
Preheat the grill to 350 degrees Fahrenheit.
Grill chicken for just enough time to get sear marks on both sides, and to give it a grilled look and flavor, about 2 to 4 minutes per side.
