A sunny day in the upper 80's put me in the mood for something cool and simple for lunch. A tuna salad sandwich sounded spot-on, but the red onion I had in the fridge was sadly moldy. Tuna just isn't the same without a little crunch in it, so I uncovered some healthy looking scallions, and decided to toss them on the grill I had going to prep some dinner fixings for later tonight. While I was at it I figured I should grill the rye bread too, and I ended up with a delicious tuna salad sandwich with garden lettuce and grilled scallions on grilled rye toast. A surprise great summer sandwich.
