If it’s a pressure canner absolutely you can process meat and low acid veggies. I did it for 20+ years. had one of those 2 story tall ones. the pressure canner should have a booklet, if you don’t have one look online for a booklet should give you the pounds of pressure and time.
Water bath canners only good for high acid, tomatoes, fruit, etc.
also, with tomatoes, the big seed companies have made them to be not so acidic as they were many yrs ago, so when you do can them, add some extra lemon juice to each jar....
