Shrimp Linguine

We like this for dinner last night. We think we would've liked it better had I followed the recipe.

Here's the actual recipe with all my improvs in parenthesis:
Ingredients:
3/4 pound uncooked shell-on medium shrimp (about 20-30), peeled, deveined and tails removed (I used frozen, pre-cooked shrimp that was already peeled and deveined)
3/4 c. coarsely chopped carrots
2 large plum tomatoes, seeded and diced (didn't have any because they're not fresh - used 1 can diced tomatoes, drained)
1/4 c. sliced green onions with tops (used a 1/4 of a red onion)
1/3 c. grated fresh Parmesan cheese
8 oz. uncooked linguine (used whole-wheat spaghetti)
1 tsp. olive oil
2 garlic cloves, pressed
3/4 c. sour cream (used fat-free, only about 1/2 cup)
1/2 c. fat-free evaporated milk (used about 3/4 cup since I didn't have as much sour cream)
1/4 c. snipped fresh basil leaves (used dried)
1/2 tsp. salt
1/4 tsp. black pepper
Additional Parmesan cheese

Directions:
1. Remove tails from shrimp. Cook pasta according to package; drain, return to pot and keep warm. Meanwhile, heat oil in a large skilled - add shrimp, carrots, and garlic. Cook and stir over medium heat 3-4 minutes; remove from skillet and keep warm. Gently heat sour cream and evaporated milk in same skilled over low heat. Stir in Parmesan cheese. Add shrimp mixture, tomatoes, onions, basil, salt, and pepper. Mix gently. Pour over past; toss gently to coat. Serve with additional parmesan cheese.
