How to Make It
Heat a small saucepan over medium-low. Add oil and garlic; cook, stirring occasionally and adjusting the heat as needed to keep garlic from browning too quickly, 25 to 30 minutes or until garlic is very soft. Drain oil into a small bowl; reserve oil. Place garlic cloves, eggs, and cottage cheese in a food processor; process until smooth. Transfer mixture to a medium bowl.
Preheat broiler with oven rack 6 inches from heat. Trim Broccolini stems from tops; cut tops and stems into bite-size pieces. Heat a 10-inch nonstick ovenproof skillet over medium-high. Add 1 1/2 teaspoons reserved garlic oil to pan; swirl to coat. Add Broccolini stems, bell pepper, and onion; cook, stirring often, 5 minutes or until vegetables are slightly tender. Add Broccolini tops; cook 5 to 6 minutes or until Broccolini is bright green and bell peppers are tender. Fold vegetable mixture, parsley, oregano, salt, and black pepper into egg mixture.
Heat 1 1/2 teaspoons garlic oil in skillet over medium-high; swirl to coat. Pour egg mixture into skillet; cook 30 seconds. Reduce heat to medium-low; cook, without stirring, until eggs are partially cooked, about 4 minutes.
Transfer skillet to oven; broil until eggs are set and top of frittata is lightly browned, about 5 minutes. Remove from oven; run a spatula around edges of frittata to loosen. Cut into 8 wedges. Serve immediately.
