"Meatballs" don't need to contain any meat at all to be umami-rich and delicious — you just need to get a bit creative! The recipe below allows you to create meatballs out of a combination of protein-rich lentils and umami-rich mushrooms, for meatballs that are delicious served over pasta or on their own.
Of course, you'll need to add a few more ingredients to give these meatballs the pizzazz they need. Sun-dried tomatoes and Parmesan add richness and even more umami flavor, while breadcrumbs and egg give them the ideal texture. Consider cooking the lentils and mushrooms the day before so that all of your ingredients are cold when you begin; this will allow the meatballs to hold together even better.
