Is That Cheating? - Skillet Tuna Supreme

So here's a recipe I used to make quite often. Doug even recognized it as soon as he saw it! So here's the thing - I didn't have any soy sauce! I'm never without soy sauce. So I didn't have that, and then I didn't want to waste a whole lemon for a little zest. Other than that, I guess it's all there. Oh, and I only used one can of tuna - which was plenty. No tuna taste here - we like this one.
