Honestly, if you can find it local/have time for it to be delivered, you can use transglutaminase or "meat glue". It works incredibly well, and you should be able to reconstitute a roast from steaks. You can even fuse dissimilar meats together!

I haven't used this brand before, but this is what I'm talking about: https://www.amazon.com/Transglutaminase-Meat-Glue-Formula-50g/dp/B00EIGV7MC/ref=sr\_1\_5?crid=12U5GE8BVNSAE&keywords=transglutaminase&qid=1640115707&sprefix=transglutaminase%2Caps%2C156&sr=8-5
