Cut out a circle from the sheet of nori, about 3 inches across. Cut out a smaller circle, about 2 inches across. Cut out two thin strips of nori one slightly longer than the other, for the antennas.
Use the two circles as templates to cut out circles from the slice of cheese. For the smaller cheese circle, cut a small piece across the bottom to form a flat edge. Attach the cheese circles to the nori base using honey, mayonnaise, or peanut butter.
For BB-8's head, cut out two thin strips of nori and attach to the upper and lower parts of the smaller circle. Cut out a small circle from the nori for the eye and a smaller one to attach just below it to the right. Add a dot of provolone cheese over the nori eye. Cut out strips of cheddar cheese and attach around the nori to finish decorating the head.
For BB-8's body, use a small circle cutter to create two circles from the cheddar cheese slice. Use a smaller circle cutter or an exacto/paring knife to cut out the center. Cut one of the circles in half. Attach the intact circle to the top left corner of the body. Arrange the two half along the right side and bottom.
Place a piece of nori inside each of the circles on the body. Cut out strips of nori and use to connect each of the circles. Use a punch or scissors to cut out small circles from the nori and attach along the lines of nori to further decorate. Add little pieces of cheddar cheese around the insides of the orange circles to finish the BB-8.
Use a mini star cutter to cut out stars from the remaining scraps of cheese. Sprinkle over the blueberries.
Place the salad in the top tier, storing the desired dressing separately.
