Heat the olive oil in a skillet over medium high heat. Add the patties and cook to your preference, about 3 minutes per side.
Make teeth – cut some triangles out on 1 side of each Cheddar slice.
Make ears – cut 4 long triangles from the capsicum and insert into small cuts in the top of the burger buns.
Make eyes – insert 1 candy eyeball into each black olive slice and insert the eyes into small cuts on the top of the burger buns.
Make tongues – slice the pickled cucumber lengthways.
Assemble monster burgers: Take a bun base and spread with a tablespoon of garlic aioli, add lettuce leaves, tomato slices, a cooked burger patty, cheese slice teeth, and the pickled cucumber tongue hanging out. Then carefully spread some tomato sauce over the top of the teeth and cover with a bun top.
