I found it on syns online. Chilli and rice is 6. No mention of nachos? If be surprised if you could have them as well for 6 syns as they have no free food value and will undoubtably be higher than 120kcal irrespective of any syns in the chilli for oil etc.
Even a small portion is listed at 32 syns n
Is it possible that the jacket is a larger portion or comes with butter included?
