In a large bowl, add water, peppercorns, sliced garlic head, bay leaf and freshly squeezed lemon juice and lemons.
Cube up the presa pork or boneless pork roast into bite size cubes. Add to the water marinade and let it soak up the flavors for at least 1 hour.
Skewer the marinated pork cubes onto metal skewers, drizzle with olive oil and season with salt.
Preheat the grill to 375 degrees and set for direct heat.
Place the pork skewers on the grates and grill 3 minutes per side. Continue to flip to ensure even cook throughout.
Once the internal temperature of the pork reaches 140 degrees, remove it off the grill and let it rest.
To make the Tzatziki sauce, in a mixing bowl add plain Greek yogurt, shred in cucumber, freshly squeeze lemon juice, dill, Italian seasoning and salt. Mix the ingredients together.
Toast a pita bread, spread the homemade tzatziki sauce, grilled pork, sliced tomatoes, cucumber, sliced red onions and fresh dill.
Notes
Can't find Presa steak? Get a boneless pork roast.If you are using wooden skewers, make sure to soak them in water before using on the grill.
