HELP! can I use defrosted beefburgers to make spag bol?

[patienceplease]

Long story but just had some what should be frozen beefburgers given to me - were defrosted last night and kept in fridge. We don't really want to eat them as they are as we had beefburgers at BBQ last night. Can I break them up and make into spag bol/ chilli concarne?
Or any other ideas to jazz up boring tesco beefburgers?

or roll them up into meatballs?

are they very good quality burgers? If they are the kind that basically consist of still-indentifiable chunks of sesoned mince formed into a patty, then probably.

If they are flat gelatinous cheap burgery burgers, then I think it would be unspeakably gross.

Just leave them as burgers and serve them in a different way?

sorrento I thought of that but then couldn't think of a different way. I like the idea of meat balls - then I could make a sauce using up everything in the fridge (gonig away tomorrow) and maybe add some chilli in case they are unspeakably gross!
I just wanted a second opinoin about whether it was a bonkers idea to use them at all!

Lateral thinking in the kitchen - love it!
