Heat a large pan to medium heat and add a bit of olive oil. Add onion and serrano pepper and cook about 5 minutes to soften.

Add garlic and cook 1 more minute, stirring. Add to a mixing bowl and cool.

Add ground pork, bread crumbs and spicy mustard. Dash in your favorite Cajun seasonings, or a nice and spicy chili powder blend, and salt and pepper.

Hand mix and form 2 burger patties. Do not overmix. Keep it lumpy.

Heat a grill to medium heat and add the patties. Cook about 4-5 minutes per side, until pork burgers are cooked through.

While pork burgers are cooking, rub the pineapple slices with olive oil. Sprinkle with Cajun seasonings and salt.

Grill each pineapple slice a couple minutes per side. Get those nice grill marks, yo!

Toss the buns on the grill to get them toasty. You can add a bit of olive oil to them to help this along, but a dry toasting is fine.

Add the burgers to the bun and top with pineapple slices, or the other way around. Your choice!

Serve!
