Place a small roasting pan in oven. Preheat oven to 425° (keep pan in the oven as it preheats).
While oven preheats, cook bacon slice in a small skillet over medium heat until crisp. Remove bacon from pan, and crumble. Reserve the drippings.
Drizzle bacon drippings and canola oil into preheated roasting pan; swirl to coat. Add mushroom blend to pan; stir. Bake mushrooms at 425° for 8 minutes. Add haricots verts, and sprinkle with kosher salt and freshly ground black pepper; toss. Bake at 425° for 8 minutes or until beans are lightly browned and crisp-tender. Toss with reserved bacon, parsley, and minced garlic.
