Combine the rice with 1 2/3 cups water in a medium pot. Bring to a boil, reduce to a simmer and cover. Cook for 15 minutes, then turn off the heat and let sit for 5 minutes before uncovering and fluffing.
In a large bowl, whisk together the greek yogurt, sriracha, garlic powder, paprika, and salt.
Toss the cubed chicken in the marinade and let it sit for at least 5-10 minutes.
Meanwhile, use a peeler to peel the entire cucumber and the carrots into ribbons for the pickled mixture. Cut all strips in half so they aren’t so long.
Mix all the Quick Pickled Cucumber/Carrots ingredients (except for the carrots and cucumbers) in a glass jar (microwave safe) and microwave for 1 minute until boiling. Carefully pack the ribboned cucumber and carrot into the glass. Set aside for later.
Heat a skillet over medium-high heat with 1 1/2 Tablespoons avocado oil.
Cook the chicken for about 5-7 minutes per side, or until golden brown and fully cooked.
Remove from heat and keep warm, set aside.
In another medium bowl or glass measuring cup, mix together all the Ranch Sauce ingredients.
Assemble each bowl with: cooked rice, chicken, pickled vegetables, grape tomatoes, avocado (optional), a drizzle of the ranch dressing, and fresh dill and/or parsley.
