Place the bulgur in a large bowl and add 2 cups of water. Let the bulgur stand for about one hour, until the liquid is absorbed and the bulgur expanded.
While the bulgur is soaking, place the spinach in a steamer basket and steam for a few minutes to wilt. Remove, cool, and chop.
When the bulgur is ready, add steamed spinach, pumpkin seeds, tomatoes, and avocado.
Mix in the lemon juice and zest, olive oil, salt, and pepper.
Serve at room temperature.
