A nice, simple, refreshing salad is the perfect side dish for hearty mushroom ragu. We like a simple arugula salad with a lemon vinaigrette, or something with citrus for acidity to cut the richness of the pasta. I also love serving this vegan ragu with some crusty, warm bread. I know, lots of carbs, but there's no better way to soak up all of that delicious sauce!
