1. Bring a large pot of water to a boil. While the water is heating, measure remaining ingredients.
2. Add the ravioli to the boiling water and cook for 5 minutes. Add the soybeans and cook an additional 1–2 minutes or until tender. Drain the ravioli and soybeans, reserving 1/4 cup of the cooking liquid.
3. Return ravioli to the pot and stir in thyme. Whisk together sour cream, Parmesan, salt, pepper, and reserved cooking liquid. Toss the pasta mixture with the sour cream mixture, divide among 4 bowls, and serve immediately.
