Make the sauce. In a small bowl, whisk together mayonnaise, ketchup, mustard, pickle juice, minced pickles, smoked paprika, salt, and pepper.
Taste and adjust acidity or sweetness to your liking. Chill while you cook the chicken.
Prep your base and toppings. Chop the lettuce, slice the onions and pickles, halve the tomatoes, and dice the avocado. If using rice or cauliflower rice, warm it and fluff with a fork.
Set everything aside.
Season the chicken. In a medium bowl, mix the ground chicken with salt, pepper, onion powder, garlic powder, and smoked paprika. Don’t overwork it—just combine until spices are evenly distributed.
Brown the chicken. Heat the oil in a large skillet over medium-high. Add the chicken and break it into crumbles.
Let it sear for 2–3 minutes before stirring so you get some browning, then cook until no longer pink, about 5–7 minutes total.
Add burger flavor. Stir in the tomato paste, mustard, and Worcestershire. Cook for 1–2 minutes until it smells like a burger stand. If it looks dry, add a splash of water to loosen.
Melt the cheese. Sprinkle the shredded cheddar or diced American over the hot chicken.
Turn off the heat and cover for 1–2 minutes until the cheese melts. Gently toss to combine into cheesy crumbles.
Assemble the bowls. Divide greens and rice (if using) among bowls. Spoon on the cheesy chicken.
Add tomatoes, red onion, pickles, and avocado. Drizzle with the special sauce and finish with sesame seeds if you like.
Serve. Enjoy right away while the chicken is warm and the greens are crisp.
