Mediterranean Strata with Feta and Olives

Cut the bread into cubes of approximately 2 cm and set aside.

In a pan, heat the olive oil over medium heat. Add the finely chopped red onion and crushed garlic, then sauté until the onion softens and turns slightly golden. Add the zucchini cut into thin slices and sauté for a few more minutes until slightly softened. Remove the pan from the heat and let the mixture cool.

In a large bowl, mix the bread cubes, halved cherry tomatoes, sliced olives, crumbled feta cheese, and grated mozzarella.
