1. Mix together the chia seeds and water in a bowl, stirring well. Set aside until it becomes gel-like, about 15 minutes.
2. Whisk together the chia seed gel, white balsamic, dijon mustard, chilli flakes, maple syrup and minced garlic. Season with salt and pepper to taste.
3. Rinse the radicchio and pat dry. Cut radicchio in half and separate the leaves into serving shells.
4. In a large salad bowl, add in the cooked quinoa, white beans, pomegranate seeds, diced bell pepper and red onions. Pour some prepared chia seed vinaigrette into the salad. Toss until well blended. Spoon the salad into the radicchio shells. Garnish with chives and onion rings.
