1. Prep the fillings: Warm pulled mojo pork and sliced ham in a skillet over low. Keep Swiss cheese, pickles, and mustard at hand.
2. Butter & build: Split 4 sweet egg buns. Butter the outsides lightly. Spread mustard on the inside bottoms. Layer cheese, warm pork (about 3 oz), ham (2 oz), pickle chips, and another slice of cheese. Close the buns.
3. Press & toast: Heat a sandwich press or cast‑iron grill pan to medium‑high. Place sandwiches, press firmly (or weight with a second skillet), and cook 3‑4 min per side until the cheese melts and the exterior is deep golden. Slice on the bias and serve.
