MARINATE: Combine the oil, lemon juice, harissa, smoked paprika, thyme, garlic, cumin, onion, and cayenne in a bowl. When mixed, add the chicken and mix until evenly coated. Allow the chicken to marinate for 30 minutes at room temperature or covered in the refrigerator for up to 8 hours. Prepare the rice while the chicken marinates.
COOK: Heat a 12-inch skillet over medium-high heat. Add the chicken and cook it through for about 4-6 minutes, flipping as needed to brown all sides. When the chicken is almost done, drizzle with honey and cook for 1 minute before removing from heat.
ASSEMBLE BOWLS: Add the greens, rice, roasted corn, hummus, Persian cucumbers, avocados, pickled onions, and prepared chicken to each bowl. Drizzle with the feta sauce (recipe in notes) and serve.
