To make the pesto: In a food processor
, combine the olives, onion, pine nuts
, and garlic, and blend
for 1 minute. With the motor running, slowly add the olive oil until it forms a thick, smooth paste. Allow to stand 1/2 hour before using.
In a heavy 4-quart saucepan, place the chanterelles, crimini, oyster, and yellow foot mushrooms, the red onion, chili flakes, scallions
, garlic, tomatoes, and tomato sauce and bring to a boil. Add wine
after 8 minutes of cooking. Lower the heat so that the mixture simmers, partially covered, for 15 minutes.
In the meantime, preheat the grill
After simmering, the mushroom mixture should be thick, like a ragu
. Season the hodgepodge, to taste, with salt and pepper, and pour into a large, shallow serving bowl.
Toast the bread and smear with the green olive pesto
. Stand the crostini
at fun angles in middle of mushroom hodge-podge and serve immediately in center of table. Serve on top of grilled bread.
