The best lunch. A Green Goddess Tuna Melt all warm and... melty. I'm obsessed. The bubbly and gooey cheese. The simplicity of canned tuna. The deliciousness that was Tuesday's Healthy Green Goddess Dressing holding it all together. I love. You will love.  Yep. This is a MAYO-FREE tuna salad sandwich, friends! And it's delicious. Oh mayo.
