Heat oven to 425F / 218C. Place one oven rack in the lower third and one oven rack in the upper third of the oven.
Heat a 10.5” to 12” (26 cm to 30 cm) oven-safe skillet over medium-high heat. Add oil (portion for frittata) and then spinach and garlic with some salt. Saute until garlic is fragrant and any remaining liquid in the spinach has cooked off, 2 to 3 minutes.
Pour eggs over spinach and stir to combine. Fold in cheese so that it is evenly distributed throughout the eggs.
Transfer frittata to lower rack of the oven. Bake until the top is golden and a knife inserted in the center comes out clean, 18 to 25 minutes.
As soon as the frittata is baking, toss Brussels sprouts with oil (portion for sprouts), vinegar, mustard, and some salt and pepper. Spread out on a sheet pan.
Place Brussels sprouts on the upper oven rack. Roast, shaking the pan halfway through cooking, until tender, 15 to 20 minutes (depending on size).
Toss Brussels sprouts with lemon juice.
Slice frittata and serve with Brussels sprouts on the side. Enjoy!
