What's for Dinner: Shells with Roasted Cauliflower, Chickpeas and Ricotta

I had this recipe from a recent edition of Everday Food. I love chickpeas, and roasting them gave them a great slightly crunchy, nutty quality. I was a huge fan, but my famiy did not seem to agree, as most of the chickpeas on their plates stayed there. We've had -- and loved -- roasted cauliflower before, and I know there's a recipe for some type of pasta with roasted cauliflower that I've tried that was enjoyed more than this one. Lots of leftovers too - I have a feeling I'll be the only one enjoying them.

Shells with Roasted Cauliflower, Chickpeas and Ricotta
(from Everyday Food)

1/4 cup extra-virgin olive oil, plus more for serving
1 head cauliflower (about 2 pounds), cut into florets
1 can (15.5 ounces) chickpeas, rinsed and drained
Coarse salt and ground pepper
5 ounces crusty bread, cut into 1/2-inch pieces (2 cups)
1 pound medium shells
3 tablespoons chopped fresh parsley
1/2 cup fresh ricotta

Directions

1. Preheat oven to 425 degrees, with racks in upper and lower thirds. On a rimmed baking sheet, toss together 2 tablespoons oil, cauliflower, and chickpeas; season with salt and pepper. Arrange cauliflower and chickpeas in a single layer and roast until cauliflower is tender and chickpeas are crunchy, 25 minutes. On another rimmed baking sheet, arrange bread in a single layer and toast until golden and crisp, 10 minutes.
2. Meanwhile, in a large pot of boiling salted water, cook pasta until al dente. Drain pasta and return to pot. Add cauliflower mixture, 2 tablespoons oil, and parsley. Season with salt and pepper and toss to combine. To serve, top with croutons and ricotta, then drizzle with oil.
