Normally, the frittatas I make for me and my family consist of eggs, garden vegetables and cheese, but I had leftover mashed potatoes in the fridge from the day before, so I decided to throw them in and tah dah--Mashed Potato Frittata!
This is a forgiving and crowd-pleasing appetizer that you can easily modify by using different seasonal toppings. You can prepare the polenta up to 2 days in advance, and the tapenade up to 3 days. On the day of your party, simply broil the polenta squares and top them with the tapenade.
