Grilled Vegetable Sandwich
  1. In a large bowl, toss zucchini, eggplant, pepper, tomatoes and onion with 2 tablespoon (30 mL) of olive oil, salt and pepper and grill to desired doneness.
  2. Brush bread with remaining oil and lightly grill on both sides. Rub each slice of bread gently with garlic.
  3. Spoon 1 tablespoon (15 mL) of lemon walnut aioli on two slices of bread, and place 1/4 of the grilled vegetables between the slices. Repeat with remaining bread and vegetables.

Optional: Garnish sandwiches with basil leaves.

Tips: The lemon walnut aioli tastes great with grilled chicken. The aioli can also be used as a burger spread or as a veggie dip.

Toasting Walnuts
  • Baking: Preheat oven to 350°F (180°C). Arrange walnuts on a cookie sheet in a single layer. Bake 8 to 10 minutes, checking frequently.
  • Stovetop: Cook walnuts in a skillet at medium-high heat for 3 to 5 minutes, stirring frequently.
