In a medium bowl, mix together the ground beef or lamb with the ground cumin, paprika, yellow mustard, and Worcestershire sauce. Form 4 equal patties.

In a small food processor, blend the goat cheese, ground cumin, and cilantro until smooth.

Heat a cast iron pan over medium heat and cook the halloumi for about 1 minute per side. Remove and set aside. Add the burgers and cook 4 to 5 minutes per side, depending on doneness preference. During the last 2 minutes of cooking, add the halloumi on top and cover the pan with a lid. Remove the burgers from the pan and toast the buns, if desired, for about 1 minute each.

Smear about 2 tablespoons of hummus on the bottom bun. Top with the burger and layer roasted red peppers on top. Smear goat cheese on the top bun and then dollop about 2 to 4 tablespoons of tzatziki on top. Top the burger and serve immediately. Great paired with Greek salad and fries! Enjoy!
