Bring a large pot of salted water to a boil.

In a large saute pan with sides saute garlic and onion in 3 tablespoons olive oil until softened and fragrant, about 3 minutes.

Once water comes to a boil, drop in broccoli rabe and blanch for 1-2 minutes. Remove, drain and set aside.

Add red pepper flakes and sundried tomatoes to onions & garlic and cook another minute.

Add broccoli rabe to saute pan and season generously with salt & pepper.

Once water has come back to a boil, add pasta and cook for 8 minutes (slightly under done)

While pasta is cooking, add chickpeas to broccoli rabe mixture and reduce heat to medium-low. Add a bit more olive oil if the mixture becomes too dry.

Once pasta is done, drain into a colander and return to the pot. Add the broccoli rabe mixture to the pasta pot and stir to combine. Season generously again to taste. Add another tablespoon or so of olive oil to keep pasta from sticking. Add 1 1/2 cup of the grated parmesan and toss to combine the pasta mixture.

Pour pasta into a greased oven safe bowl and top with remaining parmesan cheese.

Bake for 15 minutes, broiling the last couple minutes to brown the cheese if desired.

Serve hot.
