Preheat oven to 400 degrees F.
Remove the woody ends from the asparagus by snapping them off.
Toss the asparagus with 2 tablespoons of oil, salt, garlic powder, and black pepper till each spear is coated.
Place the asparagus on a parchment lined sheet pan in a single layer.
Roast for 15 minutes or until tender. Remove from the oven and allow to cool for 5 minutes before cutting spears into thirds.
Toss the asparagus pieces in a large bowl with the white beans, dill, and capers.
Whisk together, 1 tablespoon of oil, lemon juice, tahini, paprika, sea salt, and black pepper in a small bowl. If the dressing is too thick, add ½ a tablespoon of water at a time till the desired consistency is reached.
Pour the dressing over the asparagus bean mixture and toss to combine.
Serve immediately.
