Begin by hand-grating your sharp yellow cheddar and pepper jack cheese.
Drain the pimento slices thoroughly and chop them into smaller pieces if necessary.
Chop the green onions finely using both the white and green parts.
In a medium-sized mixing bowl, combine the grated cheddar and pepper jack cheese, chopped pimento, green onions, mayonnaise, kosher salt, black pepper, sugar, and hot sauce.
Using a spatula, mix all the ingredients together until they are well combined.
Taste your pimento cheese and adjust the seasoning if necessary.
Chill in the refrigerator for at least an hour before serving.
