Blackened Tuna Atop Arugula and Baby Romaine Blend

I found the freshest tuna and pan-seared it with blackening seasoning. And, olive oil.
I make the spice blend with cayenne, garlic powder, onion powder, white pepper (if I have it) and black pepper if not and paprika.
I put this on top of arugula and baby romaine with feta, kalamata olives and 3 kinds of tomatoes.

And, with this, I added bacon, avocado, shiitake mushroom and pear Gorgonzola vinaigrette.
