Bring a large pot of water to a boil. Salt generously and cook the raviolis per package instructions. Drain, but reserve about one cup of the hot pasta water (important!).

In the meantime, make the sun-dried tomato pesto by pulsing the sun-dried tomatoes, garlic, pepper flakes, olive oil, thyme, and salt in a food processor until it comes together into a textured crumble. Add the walnuts, and pulse a few more times - see photo. Set aside.

Combine 1/2 cup of the reserved pasta water in a large mixing bowl along with two-thirds of the sun-dried tomato pesto. Add the cooked raviolis and gently toss. Add more of the hot pasta water if needed to thin the pesto out - it should make a nice chunky sauce. Taste and add more of the pesto if you like - it's really a matter of personal preference at this point.

Arrange the baby spinach on a large platter and top with everything from the ravioli mixing bowl. Top with the cherry tomatoes and a bit of crumbled goat cheese.
