    We love a thick slice of grilled onion on our good! But you have taken it up a few levels with the balsamic (another favorite of ours...why didn't I already think to do this?!?), and the chipotle ketchup - love a new way to flavor a burger...thanks, my dear - you are the best!!
    PS - and I agree 100 with "no squishy, squishy with the spatula" - you are too funny (but so right!).
