Cook the bacon. Lay bacon in a cold skillet, turn heat to medium, and cook until crisp. Transfer to a paper towel–lined plate and crumble once cooled.
Pour off most of the bacon fat, leaving a thin layer if you plan to cook the chicken in the same pan for extra flavor.
Season the chicken. Pat chicken dry. Mix garlic powder, onion powder, smoked paprika, thyme, salt, and pepper. Rub the seasoning blend all over the chicken.
Cook the chicken. Heat olive oil (or a little reserved bacon fat) over medium-high.
Sear chicken 5–7 minutes per side, until cooked through and juices run clear (internal temp 165°F/74°C). Rest 5 minutes, then slice or dice.
Prep the base. Warm cooked brown rice or quinoa, or sauté cauliflower rice with a pinch of salt and pepper until tender. Fluff and portion into bowls.
Make the ranch. In a bowl, whisk Greek yogurt, mayonnaise, lemon juice, Dijon, and ranch seasoning.
Add water a little at a time until it’s drizzle-ready. Taste and adjust salt, pepper, or lemon.
Prep the veggies. Halve tomatoes, dice cucumber, slice onion thinly, and chop the greens. If using canned corn, drain well; if frozen, thaw and pat dry.
Assemble the bowls. To each bowl, add your base.
Top with greens, chicken, bacon crumbles, tomatoes, cucumber, corn, and onion. Drizzle generously with ranch.
Add the extras. Finish with avocado, herbs, a small sprinkle of cheese, or jalapeños if you like heat.
Serve or store. Enjoy right away, or pack into meal-prep containers with the ranch on the side.
