On the SW website syns section the jackets at Spoons have LOADS of syns, hence the stories about what Spoons do to their jackets - Spoons tell you they are literally dug up for the ground and baked.
I have avoided Spoons jackets as I'm not sure who to trust and don't wanna risk going over my syns inadvertently, but there are many who are happy to have jacket with beans no butter/dressing etc and have it syn free. You'll have to make up your own mind.
I ALWAYS have the 5 bean chilli which is GAWWWWJUSSSSS!! But if you have this it has to be with the yellow basmati rice (not chips) to be 4.5 syns. And if you leave the tortilla chips alone it is TOTALLY SYN FREE
