Combine oil and garlic.
Spread cut sides of rolls evenly with mustard. Place 1 cheese slice, 2 bacon halves, 3 pickle slices, and 1/2 teaspoon cilantro on bottom half of each roll. Divide ham and turkey evenly among bottom halves of rolls; top each serving with 1 cheese slice and top half of roll. Brush garlic oil evenly over outside of rolls.
Heat a large nonstick skillet over medium heat. Add 2 sandwiches to pan. Place a cast-iron or heavy skillet on top of sandwiches, and press gently to flatten. Cook 3 minutes on each side or until cheese melts and bread is toasted (leave cast-iron skillet on sandwiches while they cook). Repeat with remaining sandwiches.
