Cook the pasta according to package directions, then drain.
Meanwhile, heat the oil in a large skillet. Add the garlic and sauté for a minute or two over low heat, just until golden.
Add the broccoli to the skillet along with about ¼ cup water. Cover and steam over medium heat until the broccoli is bright green and just a little beyond tender-crisp. Remove from the heat.
Combine the cooked pasta with the broccoli mixture (along with any liquid remaining in the pan) and dried tomatoes in a serving container. Toss together and season with salt and pepper.
Serve at once, passing around dried hot red pepper flakes, and lemon or lime wedges if desired for embellishing individual portions.
