If you’re looking to use another kind of tuna, yes, you can use any other brand in this.   It’s so good with Island Trollers, but if you don’t have any (and you should really try it!), I recommend a good quality tuna that’s sustainably caught. There are many brands at the grocery store now.   You’ll want 2 cans of 5–6-ounce cans. Albacore tuna will have the best flavor. Other tunas will work as well. Preferably packed in olive oil. Then, drained and broken into ½-inch chunks.
