Farro thickens and gives substance to this dish that is a cross between a stew and a saute. The result has just enough liquid that you'll want a good loaf of bread to use for soaking up the flavorful sauce.
Heat a Dutch oven or saute pan with a lid with oil over medium heat. Add soyrizo and cook, breaking it apart, until browned, 8 to 10 minutes.
Add mushrooms and garlic to pan and cook until mushrooms are starting to soften, 2 to 3 minutes.
Pour wine into pan and bring to a simmer. Simmer for 1 minute.
Stir in stock, zucchini, farro, and tomatoes (including liquid). Bring to a boil. Reduce to a simmer and cover. Simmer until farro is tender, ~25 minutes.
When stew is nearly finished, toast baguette. (You can spread the toasted baguette slices with some butter or brush them with some olive oil if you’d like.)
When farro is tender, stir beans and lemon juice into stew. Taste and season with some salt, pepper, and / or more lemon juice if you’d like.
