Mix cream cheese with the cheddar cheese, parmesan cheese, pimentos, garlic salt and mayonnaise.
Spread about 3 to 4 Tbsp of this mixture evenly on each tortilla then lay 3-4 slices of ham flat on top of the cheese mixture to cover in a single layer.
Roll the tortilla up gently, yet tightly to make sure it holds together and keeps its shape.
Refrigerate for about 30 minutes to firm up the softened cheese. Cut off ends of tortilla roll and cut into 1-inch slices.
