Potatoes, Onions and Fennel

I found this recipe in a pizza cookbook from my library. It was a filling for a calzone. I loved the combination. We often omit the fennel and add bacon for added depth. In fact we had this last night for dinner. I love the potatoes with carmalized fried onions. And it's a really inexpensive dish that's rather filling.
Top a pizza crust or stuff a calzone, use for a pie. The options are endless. We ate this as our main dish with slices of cheese and sprouts.
We microwaved the potatoes until they were mostly soft before slicing for frying.
