How to Make It
Bring water to a boil in a small saucepan; stir in bulgur. Remove from heat; cover and let stand 15 minutes. Drain well, and let cool.
Combine bulgur, diced cucumber, green peas, and diced onion in a bowl, and toss gently. Combine yogurt and next 8 ingredients (yogurt through garlic) in a bowl, and stir well. Pour yogurt mixture over bulgur mixture, and toss gently.
Core tomatoes, and cut each into 6 wedges, cutting to, but not through, base of tomato. Spread tomato wedges slightly apart, and place on serving plates. Sprinkle 1/8 teaspoon salt evenly over tomatoes, and spoon 1/2 cup bulgur mixture into each tomato.
