Give ketchup the night off.
Harissa is a Tunisian ingredient
made from a combination of sweet
red peppers, chilies, garlic and
spices. Though a little on the
spicy side, harissa is the perfect
condiment for these burgers. Its
complex flavors meld into a subtle
background that lets the stars of
this dish shine. Just a dab of
harissa will accent the bright,
peppery mint, juicy lamb and rich,
crumbled feta of this tasty burger.
