Ingredients
Preparation
Step 1
Heat oil in heavy large pot over medium-high heat. Add garlic and crushed red pepper and stir until fragrant, about 30 seconds. Add mustard greens, chard, and collard greens and toss until beginning to wilt, about 2 minutes. Remove from heat. (Can be prepared 2 hours ahead. Let stand at room temperature.)
Step 2
Prepare barbecue (medium-high heat). Grill prosciutto until beginning to crisp, about 1 minute per side. Transfer prosciutto to plate. Tear each slice lengthwise into 1-inch-wide strips; add to pot with greens. Grill clams in batches, if necessary, until each opens, about 6 minutes (discard any clams that do not open). Transfer clams from grill to pot.
Step 3
Meanwhile, cook spaghetti in another large pot of boiling salted water until just tender but still firm to bite. Drain, reserving 2 cups pasta cooking water. Add pasta to pot with greens, prosciutto, and clams. Squeeze juice from 1 lemon half over. Add parsley. Toss over medium-high heat until heated through, adding reserved pasta cooking water by 1/2 cupfuls if dry. Season with salt and pepper and more lemon juice, if desired. Transfer pasta mixture to large shallow bowl and serve.
