Heat oil in a medium sauté pan over medium heat. Add onions and garlic and sauté for about 5 minutes until just translucent and beginning to soften, stirring often, careful not to burn. Add eggplant, peppers and zucchini and sauté 5 to 10 minutes more or until just soft, stirring often, careful not to burn. Remove from the heat and stir in Sabra Matbucha or Caponata to combine.
Evenly distribute and spread Matbucha Ratatouille over 5 sheets of matzah and sprinkle with mozzarella. Place 4 to 5 small dollops of ricotta on each sheet of matzah.
Bake at 400 degrees F for 5 to 10 minutes until cheese is golden and bubbly. Using a pizza slicer, slice matzah into 4 equal squares and serve warm.
