Brown the hamburger in a skillet over medium heat with the seasoned salt, black pepper and diced onion. Cook until no longer pink and drain any excess fat.
Meanwhile combine the mayo, 2½ tbs. ketchup & hot sauce in a small dish and whisk until smooth. Spread this mixture over the base of the pizza dough with the back of a spoon. Top with the cooked ground beef.
Spread the shredded cheese over the top. Drizzle the remaining ketchup and mustard over the top of the pizza, followed by the dill pickle chips.
Bake for 6-8 minutes, or until center is bubbly and crust is golden brown. Let cool slightly before slicing. Enjoy!
