Owing Something: 'deber + [thing owed]'
When 'deber' means 'to owe', the thing that is owed comes directly after the verb. For example, 'Ellos deben el dinero' (They owe the money).
Adding 'por'

Correction: Ellos deben la comida. In English we say 'owe *for* something,' but in Spanish you just say you 'owe the thing' directly.
