Preheat oven to 375°F (190°C). Spray a large casserole dish with non-stick spray (an 8" x 12" x 3" dish or a regular 9" x 13" dish works well).
Place 1 1/2 cups cottage cheese in a fine-mesh strainer and rinse under cold running water; let it drain thoroughly.
While the cottage cheese drains, crack and beat all 16 eggs in a medium bowl until well combined.
Thinly slice the bunch of green onions. Reserve a few tablespoons of the sliced green onions for garnish and set them aside.
Put the drained cottage cheese into the prepared casserole dish.
Add the one 7 oz. can diced green chiles, 2 cups of the grated Cheddar-Jack cheese, the sliced green onions (except the reserved garnish), 1 tsp Spike Seasoning, and salt and fresh-ground black pepper to taste to the cottage cheese in the dish.
Use a fork to gently stir the ingredients in the casserole dish until evenly combined.
Pour the beaten eggs over the mixture in the casserole dish and gently stir again so the eggs are evenly distributed.
Sprinkle the remaining 3/4 cup grated Cheddar-Jack cheese evenly over the top of the casserole.
Bake uncovered for about 40 minutes, or until the eggs are firm in the center and the top is beginning to brown (shallower dishes may require a slightly shorter baking time).
Remove from the oven, garnish with the reserved sliced green onions, let cool slightly, and serve hot.
