Bring water and quinoa to a boil in a saucepan. Reduce heat to medium-low, cover, and simmer until quinoa is tender, 15 to 20 minutes. Allow to cool. Whisk orange juice, vinegar, orange zest, salt, curry powder, and pepper together in a small bowl. Slowly drizzle in olive oil, whisking continuously until well blended. Line up 5 pint jars in an assembly line fashion. Place 1 1/2 tablespoons of dressing into the bottom of each jar. Place 1/2 cup cooked quinoa into each jar, and top with 2 tablespoons cherries. Add 1 1/2 tablespoons goat cheese on top of the cherries. Top with 1 cup of spinach per jar and pack down tightly to remove air pockets; jars should be filled to the top. Finish each jar with 1 tablespoon walnuts. Cover jars and refrigerate until ready to eat.
