10 oz crimini mushrooms, sliced
1 1/2 to 2 lb white potatoes, sliced
1 large onion, cut into thick slices
1 bunch broccolini*, roughly cut
1/4 cup olive oil
1/4 cup red wine vinegar
2 tablespoons Dijon mustard
1 tablespoon rosemary
2 garlic cloves, minced
1 shallot, minced
juice and zest of 1 lemon
Preheat grill. Brush the mushrooms, onion slices, broccolini and potatoes with olive oil. Place on a grill pan. Grill until fork tender, flipping occasionally to evenly brown.
Meanwhile, whisk together dressing ingredients. When the potatoes, mushrooms and onions are cooked through, toss them with the dressing. Serve immediately.
*Sometimes referred to as "baby broccoli", it is actually a broccoli and kai-lan (Chinese broccoli) hybrid.
