Heat the oven to 400 degrees. On a baking sheet, stir together the chickpeas, tomatoes, shallot, olive oil, honey and chile flakes. Season with salt, then spread in an even layer. Arrange the feta among the chickpeas. Roast until the feta and tomatoes are soft and the chickpeas are golden brown, 30 to 35 minutes (no need to stir). Eat right away. (The feta will harden as it cools; reheat leftovers.)
