Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper or a silicone baking mat.

Spoon 2 tablespoons of grated Parmesan cheese onto the prepared baking sheet. Lightly pat it down with your fingers to form a round shape, about 4 inches in diameter. Leave about 1/2 inch of space between each crisp.

Repeat with the remaining cheese to make 4 rounds.

Bake for 3 minutes, or until the edges are just starting to turn golden.

In a small bowl, combine the sesame seeds, dried onion flakes, dried garlic flakes, and poppy seeds.

Sprinkle about 3/4 teaspoon of the seed mixture evenly over each Parmesan round.

Bake for another 5 minutes, or until golden brown and crispy. Let cool completely on the baking sheet before eating, as they will crisp up further as they cool.
