Spread half of your mixtureit into the shape of a square in the corner
Crush your blue chips
Sprinkle the chips over the square
Cut out small circles from a slice of provolone cheese & place then on top of the crushed blue chips. (We used the end of a small icing tip to cut ours out.)
For the rest of the flag
Spoon the remaining sour cream mixture in a baggie & snip off the corner.
Squeeze out 6 lines across the shredded cheese layer to make the white stripes of the flag.
Sprinkle your diced tomatoes in between the white stripes to make the red ones.
