Citrus Pesto Tuna

I got this recipe from Weber's Real Grilling cookbook, and tried it today for my first tuna recipe. The marinade was great, although the cooking time seemed a bit short (the recipe says 3-4 minutes, turning once) so I increased it to 4 minutes per side and it was overdone. I'm including the original cooking times in this recipe, but it depends on the size of the steak, so I'll have to keep experimenting!
