Cook the bacon. Line a sheet pan with foil and bake bacon at 400°F (205°C) for 12–15 minutes until crisp.
Transfer to a paper towel–lined plate and crumble once cooled. Reserve a tablespoon of bacon fat for extra flavor if you like.
Prep your base. Cook brown rice or quinoa according to package directions. Fluff and let it cool slightly so it doesn’t steam up your containers.
For a low-carb option, sauté cauliflower rice in a little olive oil with salt and pepper until tender.
Season the chicken. Pat chicken dry. Mix salt, pepper, garlic powder, onion powder, and smoked paprika. Rub evenly on both sides.
This gives you that ranch-friendly, savory backbone without overpowering the dressing.
Cook the chicken. Heat 1 tablespoon olive oil (or reserved bacon fat) in a large skillet over medium-high. Sear chicken 4–6 minutes per side, until browned and cooked through (165°F/74°C internal). Rest for 5 minutes, then slice or dice into bite-size pieces.
Alternatively, roast at 425°F (220°C) for 18–22 minutes.
Make the ranch. Whisk Greek yogurt, mayo, milk, lemon juice, garlic, dill, chives or parsley, salt, and pepper. Taste and adjust with more herbs, lemon, or a splash of milk to thin. The dressing should be pourable but not runny.
Chop the veggies. Halve cherry tomatoes, dice cucumber and bell peppers, thinly slice red onion, and shred lettuce.
If using avocado, slice right before eating or toss with lemon juice to slow browning.
Assemble the boxes. Divide your base among containers. Add chicken, crumbled bacon, tomatoes, cucumber, bell peppers, and greens. Sprinkle with shredded cheese if using.
Keep ranch in a small lidded cup, or drizzle lightly and leave extra on the side.
Finish and label. Add lemon wedges for brightness. Label containers with the date. If you plan to reheat, keep greens and avocado in a separate container so they stay fresh.
