Very few things go better with steak than mushrooms and onions. When served on a bed of greens, then drizzled with a tasty dressing, this combination is ideal when you've worked up a hearty appetite. For a unique taste, try grilling the radicchio. It will turn brown, but tastes delicious.

Preparation Time: 15 Minutes

Cooking Time: Not Available

Barbecuing Time: 10 Minutes

Servings: 4


  • 1/3 cup (75 mL) balsamic vinegar
  • 1 clove Ontario Garlic
  • 1/2 tsp (2 mL) each salt and pepper
  • 1/3 cup (75 mL) olive oil
  • 1/2 lb (250 g) small Ontario Mushrooms
  • Vegetable oil
  • 2 filets, rib eye or strip loin steaks, about 1 1/4 lb (625 g) total
  • 6 Ontario Green Onions
  • 1 small head Ontario Radicchio
  • 1 small head Ontario leaf lettuce
  • 1 large Ontario Tomato, cut into wedges


In a small bowl, whisk vinegar with garlic, salt and pepper. Gradually whisk in olive oil. Set aside.

To grill mushrooms easily, thread them onto skewers. Brush lightly with oil; then place on greased grill over medium-high heat. Add steak to grill. Cook for 5 minutes, turning mushrooms frequently and brushing with oil if necessary; turn steak. Lightly brush green onions with oil and place on grill; cook for 3 to 5 min. more, turning onions frequently and brushing lightly with oil if necessary, until steak is rare or medium rare. Remove steak and vegetables from grill. Let steak stand about 5 min.; slice thinly on the diagonal.

Meanwhile, tear radicchio and leaf lettuce into bite-size pieces; arrange on four dinner plates. Slice green onions into 1 in. (2.5 cm) pieces. Arrange green onion, mushrooms and steak on dinner plates on top of lettuce. Garnish with tomato wedges. Whisk dressing and drizzle over salad.
