I had leftover dijon and white wine from another recipe, so I gave this a try. I substituted baby spinach in place of the elusive escarole. Baby spinach is also a time saver since it doesn't have to be chopped. The only other change I made was to add an additional teaspoon or so of dijon. Shallots, garlic, and rosemary smell wonderful together.
The stew is...unusual. Visually, it kind of resembles Italian wedding soup...that someone threw up. I had hoped the corn starch would thicken more than it did, but that's just because I prefer thick stews. Overall, this meal works. If you like strong, tangy flavors this is tasty. It needs more salt though.
