Unavailable totals are not estimated. Known allergens for these plates: milk. Check product labels and cross-contact. ## First-cook checks and limits - The publisher lists 886 calories without a serving size or complete nutrition breakdown; per-portion nutrition remains unreported. - Source crushed-tomato can size is unspecified; this adaptation retains one can and requires checking its size before shopping. Sugar is present in the source and retained, despite roundup keto framing. - The publisher does not specify the size of at least one can or bag. Check the intended package size before shopping. - Ingredient quantities are scaled from 2 original portions to four portions. Fractions of whole items may need weighing or dividing after preparation. Larger batches need extra cooking space or batches; keep thickness and endpoint checks. - Adapted from Christina Cherrier. This adaptation has not been kitchen-tested. - The source does not provide verified values for every per-portion macronutrient. Missing values stay unreported; a keto label from the publisher is not a verified net-carb total. - Safe doneness checks are added to the publisher method; timers alone do not establish doneness. ## 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 - [Christina Cherrier: Stuffed Chicken Breast with Mozzarella and Spinach](https://www.eatwell101.com/stuffed-chicken-breast-recipe) - [FoodSafety.gov: safe minimum internal temperatures](https://www.foodsafety.gov/food-safety-charts/safe-minimum-internal-temperatures) These recipes include household adaptations and recipes adapted from the linked publishers.
