Always seeking a new way to cook calamari, I came up with this:
Saute in olive oil chopped calamari heads and tentacles with chopped onion, chopped green pepper, chopped garlic, and some hot red pepper flakes. About 8 minutes.
Stuff the above in calamari bodies, about 2/3 full, stick a sprig of thyme in each and squirt some lemon inside too.
Bake at preheated 350 degrees for 20-25 minutes.
Remove from oven, douse each calamari with whatever juice is on the baking pan, additional olive oil, lemon zest and parsley.
Nice.
