Bring a large pot of water to a boil. Add bucatini and cook according to package instructions. Before draining reserve 1 cup of pasta water.
Place a pan on the stove over medium heat. Add sun-dried tomatoes, oil, cherry tomatoes, a pinch of salt & pepper, red pepper flakes and oregano to the pan and stir to combine. Cover and cook until tomatoes have softened (approx. 5 minutes).
Add frozen spinach to the pan (no need to thaw) and cover again for another 2-3 minutes.
Add the garlic, thyme, sage, hummus and pumpkin to the pan and stir to combine. Continue to heat until warm and bubbly. Turn heat off.
Add hot pasta to the pan and toss to combine. If the sauce is too thick, add pasta water as needed. Taste and adjust seasonings as needed.
Serve with fresh basil.
