Preheat your oven to 375°F (190°C).

Hollow out the centers of the bagels using a knife or a bagel slicer.

In a mixing bowl, whisk together the eggs, heavy cream, salt, and black pepper until smooth.

Fold in pre-cooked vegetables and meats into the egg mixture.

Spoon the filling mixture into each hollowed bagel, leaving some space at the top.

Place bagels on a lined baking sheet and bake for 15-18 minutes.

Let stuffed bagels cool for a few minutes before serving.
