In a skillet over low heat, melt butter; add egg mixture. As the eggs begin to thicken, use a spatula to turn them over gently. Turn portions of egg mixture with spatula as it begins to thicken; do not stir. Be careful not to overcook - 1 or 2 minutes is usually long enough; eggs should still appear moist.

Makes 4 servings.

Variation: Try orange, maple or banana yogurt instead of plain.
