Preheat oven to 425° F with rack in the center position. Butter bottom and sides of 9-inch springform pan with half the butter; set on a baking sheet.
In a nonstick skillet over medium-high heat melt remaining butter and sauté onions and peppers until tender, about 5 minutes. Add tomatoes and chopped arugula, season with salt and pepper, stir and set aside.
In a large bowl, whisk eggs and add alouette Garlic and Herbs Soft Spreadable Cheese (setting aside a scoop or two to add to the finished frittata). Add cream and whisk until smooth. Stir in shredded cheese.
Pour half of the egg mixture into prepared pan and scatter half the vegetable mixture. Repeat with remaining egg and vegetable mixture.
Transfer baking sheet and frittata to oven and bake 20 minutes, reduce heat to 350° F and continue to bake until frittata is puffed and golden and the center is set, about 60-65 minutes. Remove from oven, run a small sharp knife around sides to loosen and let rest 15 minutes. Frittata will fall slightly as it sits.
Remove collar from pan, slice and garnish top with additional alouette Garlic and Herbs Soft Spreadable Cheese, extra tomatoes and the micro greens to serve.
