There’s no better way to celebrate the earth than to eat things from it so Pierre Lafond Bistro (516 State St., 962-1455, pierrelafond.com)-in conjunction with the Community Environmental Council-has cooked up a spectacular Earth Day six-course Vegetarian Wine Pairing Dinner for April 22 at 7 p.m. Chef Joshua Keating will prepare almost too much deliciousness like the richness of eggplant cannelloni stuffed with organic spinach, caramelized onions, roasted potatoes, and garlic served with a black walnut, feta cheese, and oregano salad topped with a fresh carrot emulsification and balsamic glaze. That gets washed down with a 2004 Lafond Sangiovese for extra luxuriousness. That’s course five. All this goodness comes your way for a mere $55, tax and tip inclusive.
