Place cream cheese spread ingredients into the bowl of a food processor and pulse until everything is combined nice and smooth.
Mix mayonnaise, garlic, and salt in a bowl.
Lay out your slices of bread. Put 2 slices of cheddar on 4 of the pieces, and 2 slices of provolone on 4 of the pieces.
Heat a heavy duty skillet on medium heat.
Divide your cream cheese spread into 4 portions, and spread each portion onto the provolone halves.
Place your cheddar sliced bread on top so the cream cheese spread is sandwiched between the provolone and cheddar slices.
Spread the garlic spread onto each slice of bread.
Place a sandwich into the skillet and cook 2 minutes. Then flip the sandwich and cook 2 minutes on the other side. Bread should be golden brown and cheese should be mostly melted.
