Bring water, milk and 1 Tbsp. margarine to the boiling point in large saucepan. Stir in Knorr® Italian Sides™ - 4 Cheese Pasta and roasted peppers. Continue boiling over medium heat, stirring occasionally, 13 minutes or until pasta is tender.
Meanwhile, melt remaining 1 Tbsp. margarine in large nonstick skillet over medium-high heat and cook garlic 30 seconds. Add shrimp and cook, turning once, until shrimp turn pink, about 4 minutes. Add spinach and cook 2 minutes. Stir in hot Pasta; now it's delicious. Dig in!
