First, melt butter in a large pan on medium-high heat. Add flour and stir for about a minute until it's smooth.

Next, add garlic and cook for about 30 seconds until it smells good.

Now, mix in cream, lemon juice, Italian seasoning, and sun-dried tomatoes. Let it simmer for 2 minutes. If it bubbles too much, turn down the heat.

Then, put in the shrimp and cook for around 5 minutes until they're cooked through and the sauce thickens a bit. Be careful not to cook them too much.

After that, add spinach and basil and cook for another 2 minutes. Add salt and pepper to taste. Serve right away. If you like, squeeze extra lemon juice on top (optional). You can also sprinkle fresh parmesan on top if you want.
