1. Bring 1 1/2 cups cold water and amaranth to a boil in a medium saucepan; reduce heat, cover, and simmer 20 minutes or until water is almost absorbed (it will have the appearance of mush).
2. While amaranth cooks, combine cucumber and next 11 ingredients in a large bowl.
3. Place amaranth in a sieve, and rinse under cold running water until room temperature; drain well, pressing with the back of a spoon. Add to cucumber mixture; toss to blend. Add cheese; toss gently. Garnish with lemon wedges, if desired.
It's important that the amaranth is placed in a fine mesh sieve. The grain is so tiny that it will slip through a traditional strainer. If one is not available, place the cooked amaranth on a large baking sheet, and spread it in a thin layer so it will cool without clumping together.
