Potato and Pepper Frittata

1. 1 large Idaho potato
2. 12 large eggs
3. 1/3 cup of heavy cream
4. Salt
5. Freshly ground black pepper
6. 1 1/3 cups cubed (1-inch) day-old bread, crusts removed
7. 3 tablespoons of extra-virgin olive oil
8. 1 onion, cut into 1-inch strips
9. Red bell pepper
10. Green bell pepper
11. 1 tablespoon of unsalted butter

   This dish was pretty interesting to make and I enjoyed preparing but I cant stand onions so I could not stand to eat it because the flavor of the onion was so overpowering.
