Preheat your oven broiler.

In a small bowl, combine the drained tuna, mayonnaise, Greek yogurt, salt, pepper, and any optional additions. Mix until well blended.

Place toasted English muffin halves on a baking sheet. Spread the tuna mixture evenly on top of each half.

Place a slice of cheese over each tuna-topped muffin.

Broil for 2–3 minutes, or until the cheese is melted and bubbly.

Remove from the oven and serve warm.
