Yes it already takes into account any free food allowance.
If it's the one I'm looking at here are the ingredients
Steamed Rice; Paella Sauce; Cooked Chicken (17%); Chargrilled Red Pepper (8%); Prawns (8%); Peas (5%).Steamed Rice contains: Water, Arborio Rice, Turmeric Extract.Paella Sauce contains: Tomato, Water, Onion, Passata, White Wine, Signature™ Chicken Stock (7%) (Natural Chicken Juices, Water, Onion, Carrot), Chorizo Sausage (6%) (Pork Shoulder, Pork Belly, Salt, Paprika, Dextrin, Lactose (from Cows' Milk), Milk Proteins (from Cows' Milk), Sugar, Garlic, Dextrose, Antioxidant: Sodium Ascorbate; Rosemary Extract, Preservatives: Sodium Nitrite, Potassium Nitrate), Tomato Purée, Rapeseed Oil, Sherry Vinegar, Cornflour, Paprika Powder, Garlic Purée, Salt, Saffron, Cracked Black Pepper.Cooked Chicken contains: Chicken, Rapeseed Oil.Chargrilled Red Pepper contains: Red Pepper, Rapeseed Oil.Prawns contains: Prawn, Water, Salt.
The syns will come from the wine, chorizo, tomato puree, oil, cornflour, more oil in the chicken(!), and yet more oil on the chargrilled peppers. They could easily add up to that.
