Toss chicken thighs into a oven safe baking dish and marinate chicken with olive oil, tomato paste, greek yogurt, garlic, salt, smoked paprika, and oregano. Massage with you hands and allow to marinate for 1 hour or overnight for best results.
Preheat oven to 450F.
When chicken is down marinating, place onto a baking sheet that is lined with a wire rack. If you do not have a wire rack, no stress. Don't over crowd the pan. Bake chicken for 35-40 minutes.
While chicken is baking make the herb sauce. Toss the yogurt, herbs, jalapeno, olive oil, red wine vinegar, and salt into a blender and blend until smooth.
