McFeast features two 100% fresh beef burger patties that are hot, deliciously juicy and cooked when you order, but with a spicy double kick of jalapeno sauce, and hot spicy sauce. McDonald’s beef patties are seasoned with just a pinch of salt and pepper, sizzled on a flat iron grill, then topped with onions, slice of tomato, tangy pickles and melty cheese on a sesame seed bun.
