Make the chicken marinade. Mix the marinade ingredients in a jar.
Marinate the chicken. Add chicken thighs to a baking dish and pour over the marinade, making sure to coat all sides evenly. Marinate for at least 30 minutes, up to 8 hours.
Make the pickled onions. In a wide-mouth jar, add onions, 1/2 teaspoon salt, vinegar, and boiling water. Shake well and set aside.
When your chicken is almost done marinating, make your rice according to the package. Once done, let it cool for a few minutes. Add cilantro, lime juice, and a pinch of salt and stir well to combine.
Grill your chicken. Heat the grill to medium-high heat (around 400-450 degrees). Once hot, place the chicken close to the direct heat and grill for 6-8 minutes. Flip and move to indirect heat (not directly over fire/coals) and cook for another 5-10 minutes, depending on how thick your thighs are, or until internal temperature reaches 165 degrees.
Make the street corn. Remove the husk and excess silk. Rub the ears of corn with oil, giving them a slight coating. Once the grill is hot, place the corn directly on the grill. Cook for about 10-15 minutes, rotating every few minutes until the corn is cooked and has some char marks. Let cool for a couple of minutes and then remove the corn kernels from the cob. In a medium bowl, mix the greek yogurt, mayo, lime juice, paprika, chili powder, salt, and pepper. Add corn kernels, cotija cheese, jalapeno, cilantro, salt, and pepper to the bowl with your dressing. Mix well to combine. Adjust according to taste. Let chill in the fridge until ready to assemble.
Assemble the bowls. Evenly divide the rice, romaine, street corn salad, grilled chicken, avocado, and pickled onions. I like to top them with a squeeze of lime juice, a sprinkle of cotija cheese, and fresh cilantro.
Enjoy!
