Veggie Box onions, halved then sliced lengthwise (root to tip) in 1/4-inch thick slices
Veggie Box fennel bulb, sliced into 1/4-inch thick slices
1/4 cup extra virgin olive oil
1 Tbsp butter
Salt
1/4 cup grated Parmesan
2 tablespoons chopped fresh parsley
1 teaspoon lemon zest
2 teaspoons lemon juice

1/4 cup extra virgin olive oil 1 Tbsp butter 1/4 cup grated Parmesan 2 tablespoons chopped fresh parsley 1 teaspoon lemon zest 2 teaspoons lemon juice

Cook fennel and onions in olive oil and butter: Heat olive oil and butter in a large, uncovered, wide pan on medium high heat. Add the sliced fennel and onions and stir to coat. Stir occasionally. After about 10 minutes, sprinkle the onions and fennel with salt. Lower the temperature to medium.You want to strike a balance between allowing the pan to get hot enough so that some caramelization and keeping the pot from getting so hot that the onions and fennel dry out. If it becomes an issue, you can add a couple tablespoons of water to the pan to help the onions and fennel to keep from drying out too much. Stir occasionally, scraping up any browned bits from the bottom of the pan. Note that the browned bits are the tastiest parts. Cook for another 30 minutes to an hour. The longer you cook, the more caramelized and browned. By the way, the onions and fennel will have plenty of flavor without having to be completely cooked down and browned all over. When ready to serve, remove from heat and toss in the freshly grated Parmesan cheese, the chopped parsley, lemon zest and lemon juice. Taste and add more lemon juice if necessary.
