grilled turkey, onion, and garlic panini

for the first year or so we were married, some version of this sandwich - sometimes with bacon, others without onions - made it onto our dinner plates about once a week. full of garlicky mayo, fresh basil, melty cheese, and sauteed onions, it's the definition of quick & easy weeknight dinner.
