Yes — Roast Chicken Slice is ultra-processed.
The product is classified as ultra-processed because it contains several UPF ingredients and additives: dextrose (an industrially refined sugar), yeast extract (a flavor enhancer), stabilisers such as tetrapotassium diphosphate and disodium diphosphate (industrial stabilisers), and caramelised sugar syrup (an industrial sugar preparation). Under NOVA, the presence of these industrial formulations and additives makes the overall product UPF even though the main ingredient is chicken breast.
Other meat & poultry Nomi has checked — these ones aren't ultra-processed.
