As the winter months approach, our diets tend to shift towards heartier, more comforting dishes (and this onion tart recipe is going to satisfy that need). But that doesn’t mean we have to sacrifice nutrition for flavor. In fact, many winter vegetables are packed with vitamins, minerals and antioxidants that can help boost our immune systems and support overall health.

One of the unsung heroes of the winter vegetable world is the humble Brussels sprout. These small, cabbage-like vegetables are a rich source of vitamins C and K, as well as fiber and antioxidants. They’ve also been shown to have anti-inflammatory properties and may even help support cancer prevention.

So how can you get the most nutritional bang for your buck when it comes to Brussels sprouts? The key is to cook them in a way that preserves their delicate nutrients. Roasting is an excellent way to do this, as it helps bring out the natural sweetness in the sprouts while retaining their vitamin and mineral content.

Now, let’s get cooking!
