In a large pan, saute the chopped broccoli and diced red onions in olive oil over medium-high heat for about 5 minutes, tossing a few times.
While the broccoli cooks, combine the garlic cloves and salt in a garlic masher. Mash the garlic well and then add to the pan, cooking for another minute.
Remove the broccoli, onions and garlic to a serving bowl. Add the butter to the pan. When melted, add the tortellini and pepper. Cook for 5-7 minutes, tossing a few times so all sides become golden brown and crispy.
Remove tortellini from pan and add to the bowl of broccoli. Season with more salt and pepper as desired. Drizzle with olive oil. Sprinkle individual serving bowls with parmesan cheese if desired.
Notes
Fried tortellini and broccoli keeps well in the fridge for about a week. It reheats in the microwave well too, without causing the tortellini to lose much crispness.
