Grilled Sausage and Potato Salad with Spinach, Red Onion and Brewmaster Mustard Vinaigrette

This recipe calls for a specific kind of mustard I don't have. I don't think my substitution has the same flavors. This is a nice weeknight meal, but nothing special. I have to deconstruct the recipe a bit so my family don't think they're eating salad for dinner.

We loved this one. I couldn't find Brewmaster mustard so I used Plochman's Beer Mustard instead and it tasted great. I think this dressing would also be good on other salads. Sara gives you a side bar recipe to make your own Brewmaster mustard if you wish. I may try that sometime as well.
