Heat a large nonstick frying pan over medium heat and add about half of the olive oil.
Add the chopped red and green bell peppers and sauté until slightly softened, about 3–4 minutes.
Stir in the diced green chiles and the Spike seasoning and cook for 1–2 minutes more to heat through.
While the peppers cook, crack the eggs into a mixing bowl and whisk until fully combined.
Add a bit more olive oil to the pan, pour in the beaten eggs, reduce the heat to low, and gently stir and scrape the sides continuously with a rubber spatula until the eggs are just barely set but still slightly moist, about 6–8 minutes.
Remove the pan from heat while the eggs remain slightly wet if you plan to warm and melt cheese later (for example, in a slow cooker).
Warm tortillas briefly if desired, then divide the scrambled eggs among the 10 tortillas, sprinkle with grated cheese, and roll into burritos.
Serve immediately or place burritos in a slow cooker to keep warm and melt the cheese before serving.
