Preheat oven to 375° F and line 2 baking sheets.
In a small bowl, combine the mayo, onion, and garlic.
Roll out one package of dough separating it into the pre-cut triangles.
Spread a small spoonful of the mayonnaise mixture on each triangle, add 1 slice of ham, and 1/2 slice of cheese.
Roll up each triangle and place on lined baking sheet.
Repeat with the other roll of dough.
Bake at 375° F for 9 - 11 minutes until light golden brown. Remove from oven, plate, and serve warm.
