Tuna Roast with Ratatouille
A whole meaty tuna loin can be roasted the same way as a hunk of beef. If your loins are small--3/4 lb. or less each--you can tie them together to create a plumper-looking roast: With the widest sides together, tie at 2-in. intervals with kitchen twine. Take the tuna out of the oven when it's still very rare--albacore keeps on cooking after it's pulled off the heat, and if it's overcooked, it's dry.
