Prepare the cheeses by slicing the standard cheddar into squares and using a small star-shaped cookie cutter to press out star shapes from the white cheddar.
Place the marshmallow fruit dip in a small bowl and position it near the center of a large wooden serving tray or platter.
Arrange the larger items first, placing the mini chocolate muffins, beef salami, beef pepperoni, and the two types of cheese in distinct sections around the dip bowl.
Fill in the gaps with the fresh produce, grouping the strawberries, blueberries, red grapes, cherries, and cherry tomatoes for a vibrant pop of color.
Scatter the remaining dry goods, including butter crackers, mini pretzels, savory snack mix, granola and nut mix, and the mozzarella balls into any remaining empty spaces.
Finish the tray by sprinkling the red, white, and blue candies over the top for a festive, patriotic touch. Serve immediately or chill until ready to eat.
