Ingredient Checklist


Instructions Checklist
  • Preheat a grill to medium-high.

  • Prepare Blue Cheese Sauce. Set aside.

  • Dip a pastry brush in water, then lightly brush 1 teaspoon oil over both sides of bread. Grill (or toast) the bread, about 1 minute per side. Set aside.

  • Lightly brush tomatoes, mushrooms and onion slices with remaining 2 teaspoons oil. Season with salt and pepper. Oil the grill rack (see Tip). Grill the vegetables (or pan-sear in batches) until browned on both sides: about 1 minute per side for tomatoes, 3 to 5 minutes per side for mushrooms and onion. Cut mushrooms into 1/2-inch-thick slices and separate onion slices into rings.

  • To assemble, spread the reserved cheese sauce over the grilled bread. Divide arugula (or watercress) among the bread slices and arrange the grilled vegetables on top. Sprinkle with walnuts. Serve immediately.

Mmm mmm mmmm!!!! I love this recipe. There are a few changes I made to it that I think really kicks it up a notch. I put the onions (which I slice very thin) in a bowl and drizzle olive oil and balsamic vinegar over them and toss them. Once I put them in the skillet I add about 1/4 tsp of sugar which helps them caramelize and brings out their sweetness. I grill them until the are very brown and starting to burn a little on the tips. I toss the mushrooms with olive oil and balsamic as well and grill until brown and tender. These are awesome on a sub roll and much easier to eat! Read More

Pretty good I did not enjoy the blue cheese too much. (this was the first time I ever had it). It does taste a bit like cream cheese which is cheaper. So next time I make this sandwich I will save a few bucks and use cream cheese with a bit of lemon. Otherwise the sandwich was pretty good! If you like blue cheese this will be a great sandwich to try! Pros: Very quick and easy Read More

Loved by All! This is a great vegetarian dinner that everyone will enjoy. The walnut oil is essential as is the rustic bread. If you don't care for blue cheese I found goat cheese is just as good. Please try this - you won't be sorry. Read More

This sandwich is AWESOME! I'm not even a big mushroom lover and I despise blue cheese! I made mine with Greek yogurt and Feta cheese and we seasoned the mushrooms with onion powder garlic powder Italian seasoning & black pepper before grilling. This is absolutely a keeper. Going to serve this to guests- it's that good.:) Read More
