Yes, you can! For a slow cooker, add all the ingredients (except the pasta and kale) and cook on low for 6-8 hours or high for 3-4 hours. Add the pasta and kale in the last 15-20 minutes. For an Instant Pot, sauté the veggies, add the remaining ingredients (except the pasta and kale), and cook on high pressure for 5 minutes, then quick release. Add the pasta and kale, and use the sauté function to cook until the pasta is done.
