Combine 2 tablespoons of the hummus with the lemon zest, half the lemon juice, and just enough water to create a thin dressing. Before dividing the grains between two small bowls and adding the dressing, squeeze the grain bag to separate the grains. A handful of the spinach should be added to each bowl.
Add one half to each bowl after squeezing the remaining lemon juice over the avocado halves. Just before serving, carefully combine the remaining hummus, chicken, onion, pomegranate seeds, almonds, and almonds in one bowl.
