In a blender, put the milk, roasted red peppers, basil, oregano, crushed red peppers, salt, pepper, tomato paste, tahini and garlic. Blend until the sauce is smooth. Taste and adjust seasonings and set aside.
Mediterranean Shrimp Pasta
In a large pot or skillet, heat 2 Tablespoons olive oil over medium heat. Add the onion and garlic in and sauté for 2 minutes. Add the broth and pasta and bring to a boil over high heat. Turn the heat down to medium and simmer, stirring frequently and cook for 8 minutes until pasta is done.
Add the shrimp and a dash of salt and pepper and cook until the shrimp turns pink, about 4-5 minutes. Add the olives, tomatoes, spinach and artichokes and cook until the spinach is wilted (you will want to use your spoon to mix the spinach with the pasta dish as it wilts).
Slowly pour in the roasted red pepper sauce and simmer for 2-3 minutes until the sauce is well mixed in. Garnish with fresh parsley, crushed red pepper and the cheese of your choice.
Notes
You can modify this recipe to your tastes: you can easily use a variety of ingredients or take things out that you don't like. Try adding white beans or chickpeas, vegetables like zucchini or bell peppers, and use a variety of cheese including feta, Parmesan or mozzarella.
I like to use a small pasta when I make this dish, like orecchiette, but you can use whatever pasta you like.
