"Sausage," Cauliflower & Kale Potpie

2 Tbs olive oil
1 pkg refrigerated Italian "sausage," cut into 1/4-inch rounds
1/2 onion, chopped
1 Tbs fresh rosemary, chopped
Kosher salt and freshly ground black pepper
1/3 cup all-purpose flour
3 cups vegetable broth
1 bunch kale, torn into bite-size pieces
2 Tbs white wine vinegar
1 small head cauliflower, chopped
2 sheets puff pastry (one 17.3oz pkg)

1) Heat oven to 400F.
2) Meanwhile, heat the oil in a large skillet over medium-high heat. Add the "sausage," onion, rosemary, 1/4 tsp salt and 1/4 tsp pepper, and cook, stirring, until softened, 3 to 5 minutes. Sprinkle with the flour and cook, stirring, for 1 minute. Add the broth and simmer until thickened, 2 to 3 minutes. Add the kale, vinegar, 1/2 tsp salt and 1/4 tsp pepper and cook, tossing, until the kale is wilted, 2 to 3 minutes.
3) Pour this mixture into a large bowl and add the cauliflower, tossing until combined. Transfer to a 9x13-inch baking dish and top with the puff pastry, covering the potpie filling (1/3 of a sheet will be leftover).
4) Bake until the pastry is golden and the filling is bubbling, 25 to 30 minutes. Let cool for 5 minutes before serving.

Review: This is one of the few times where I took a recipe that used meat and made it vegetarian. Shopping for the ingredients was a chore, as we've been doing the bulk of our grocery shopping at Trader Joe's and Whole Foods. Apparently Trader Joe's does not sell a white wine vinegar. Whole Foods only sells one type and it's organic and expensive. Whole Foods had a Champagne Vinegar on sale and we snagged that, thinking it was close enough! I also lamented that Trader Joe's didn't have puff pastry anymore. Whole Foods had one brand, which cost $12 for the package. Forget that! I picked up Pepperidge Farm's puff pastry at Target for a little over $4, but I hate that they use high fructose corn syrup! Regardless, I love puff pastry and it's flaky yumminess. And, the sauce was essentially gravy, a staple of a good potpie!

And, this is what I did to the 1/3 sheet of puff pastry that was left over - make snacks!
