In a food processor or blender, combine lemon juice, avocado oil, tomato paste, onion, garlic, ginger, and all spices and pulse/blend until almost smooth. You want it to be just a tiny bit chunky.
In a tupperware or plastic bag, combine chicken chunks, processed marinade, and chopped cilantro. Marinate for 30 minutes up to 6 hours.
Turn the oven broiler on low and place the rack about 7-8 inches away from the broiler. For my oven, this is the third rack space down.
Line a large sheet pan with tin foil and spray with non-stick spray. Spread the chicken chunks evenly on the pan in one layer.
Depending on the oven, broil for 8-15 minutes. Check on them after 8 minutes; if not slightly charred on top, let go for another few minutes.
Remove, portion into meal preps. Serve with basmati rice or naan. Enjoy!
