Linguine with Roasted Summer Vegetables

Preheat oven to 450 degrees F. Combine stock and garlic in a small saucepan. Bring to a boil, reduce heat to low and simmer, covered, for 15 to 20 minutes, or until garlic is tender.

Place broth, garlic and vinegar in a blender or food processor and puree until smooth. Return to the saucepan and keep warm over low heat.

Meanwhile, combine tomatoes, asparagus, zucchini, summer squash, bell pepper and scallions in a large bowl. Drizzle oil over the top, season with salt and pepper and toss to coat well. Place on a baking sheet and roast, stirring occasionally, for 15 minutes, or until tender.

Meanwhile, cook linguine in a large pot of boiling salted water for 6 to 8 minutes, or until tender but firm. Drain and place in a large serving bowl. Toss with the roasted vegetables and garlic puree. Season with salt and pepper and serve immediately.
