## Ingredients - 680g Boneless skinless chicken thighs — raw, thawed; strips about 1 inch wide, no more than ¾ inch thick - 300g Bell pepper — sliced into ¼-inch strips. Buy by the scaled edible weight; produce size varies. - 60g Onion — sliced into ¼-inch strips. Buy by the scaled edible weight; produce size varies. - 27g Olive oil — as purchased. Half of spiced oil on vegetables; half on chicken. - 5g Mild chili powder blend - 2g Ground cumin - 2g Smoked paprika - 2g Garlic powder - 3g Fine salt. Use the proportional split described in the method. - 30g Lime juice — unsweetened - 142g Shredded lettuce — washed, ready to eat. Buy by scaled edible weight. - 150g Avocado flesh — sliced; flesh weight - 60g Plain strained Greek yogurt — plain, strained. At least 9 g protein and no more than 4 g total carbs per 100 g. ## Family starch options (per non-keto adult) - Corn tortillas: 2 count Corn tortillas — ready to eat; warm according to package. Two 6-inch tortillas totaling about 50 g per non-keto diner; check the package for wheat or gluten cross-contact. Serve alongside the bowl or fill with part of the filling; two small tortillas will not hold the whole meal. ## Equipment - Oven at 425°F on bake - Two 18×13-inch half-sheet pans - Instant-read thermometer - Microwave for family tortillas ## Cook Prepare cold sides first. Keep raw-poultry tools separate; use clean serving utensils. Probe more than one thick piece. A timer is not a doneness test. 1. **Prepare.** Heat the oven to 425°F. Prepare lettuce and avocado first. Mix oil, spices, and salt. Toss peppers and onion with half the mixture. Coat chicken separately with the rest. 2. **Cook.** Divide chicken and vegetables between two half-sheet pans in a single layer, keeping pieces apart. Bake about 18–22 minutes, until the largest chicken strips reach 165°F. No stir is needed if there is enough space; swap racks halfway if needed for your oven. 3. **Finish.** Finish with lime. Make keto bowls with lettuce, filling, avocado, and yogurt. Near the end of cooking, if serving non-keto diners, heat tortillas in the microwave according to their package for family portions; keep them wrapped until serving. Serve the measured two tortillas alongside each family bowl or fill them with part of the mixture; the full bowl portion is larger than two small tacos. ## Attention timeline - Preheat and load: 10–12 min. Prepare lettuce and avocado before raw poultry; separate chicken and vegetables on pans. - Roast: 18–22 min. Check largest chicken strips for 165°F; swap racks if needed. Heat tortillas during cook. - Finish: 2 min. Add lime; assemble measured keto bowls and separate family tortillas. Stages can overlap; endpoints and appliance behavior override the estimate. ## Flavor and capacity Roasting spaced strips concentrates pepper flavor; lime, avocado, and yogurt round out the bowl. - Measured peppers, onion, avocado, and yogurt preserve the stated keto nutrition. - Keep pieces separate so they roast rather than steam. ## Nutrition per serving Calories: 378 kcal; protein: 37.5 g; total carbs: 13.0 g; fiber: 5.9 g; net carbs: 7.1 g Per adult: base includes measured sauces, seeds and sides. Family nutrition adds one selected starch portion. US net carbs = total carbohydrate − fiber. Labels and food variation matter; no guarantee of ketosis. Known allergens for these plates: milk. Check product labels and cross-contact. ## First-cook checks and limits - Chili powder blends vary by brand and allergen label; inspect package. - Check every packaged ingredient label for additional allergens; this data is not an allergy guarantee. ## Leftovers Refrigerate in shallow containers within two hours, or one hour above 90°F. Use within 3–4 days or freeze; reheat to 165°F. Keep cold greens and yogurt separate. ## Sources - [USDA FoodData Central source data](https://fdc.nal.usda.gov/download-datasets/) - [FoodSafety.gov safe minimum temperatures](https://www.foodsafety.gov/food-safety-charts/safe-minimum-internal-temperatures) - [USDA poultry handling guidance](https://www.fsis.usda.gov/food-safety/safe-food-handling-and-preparation/poultry/chicken-farm-table) These recipes include household adaptations and recipes adapted from the linked publishers.
