Canning lomo saltado sounds like a fun experiment! While it's not a common dish to can, the key would be making sure the beef, sauce, and vegetables are safely preserved. One challenge could be the potatoes, which don’t always hold up well in canning. You might want to leave them out and add fresh ones when you serve. Also, consider pressure canning for safety since it's a meat-based dish. Would love to hear how your experiment turns out!
