According to the good folks at Whataburger (best “fast food” joint on the planet), today through the 20th is free jalapeno week. They'll add whole or sliced jalapeños to any entrée purchased for free. Add 'em to your Whataburger®, Whatachick’n®, or even a Taquito! Just mention you want free jalapeños when placing your order at any participating location.
I haven’t found a Whataburger in New Hampshire yet, but I’m still looking.
