The hub & I l-o-v-e Pita Pit.
It's a tough call (the falafel is also awesome), but I think the spicy black bean burger is our fave. It is so, so good. We thought that we'd give recreating it at home a shot & it turned out pretty great, if I do say so myself.
We cooked up a couple of pre-made spicy black bean burgers, chopped them up, & put them on a pair of tortillas. Add some veggies (we did spinach, tomatoes, banana peppers, & grilled onions) & southwest spicy mustard, and you're all set! Yes, a tortilla isn't quite a pita, but it works well enough for me! Enjoy!
