The fennel in my garden is ready to be harvested and it looks so good! Because it is grillin' season I am making this recipe in foil packets on the grill! YUMMY!

3 medium yellow onions, peeled and wedged
2 fennel bulbs, washed, trimmed and cut into wedges with fonds reserved
1 TBS good olive oil
2 TBS balsamic vinegar
salt and pepper

Preheat oven to 400 degrees.  Reserve 1/4 cup of chopped fennel fonds.
In an 8 inch baking dish, add onions and fennel bulbs. Add olive oil and vinegar. Salt and pepper. Toss to coat. Bake for 1 hour, tossing occasionally until tender and charred. Toss with reserved chopped fonds and serve.
