Preheat the oven to 400°F.
In a smaller sized bowl, add the tomato sauce, olive oil, green chiles, black olives, garlic powder, cheddar cheese, and green onions. Mix all ingredients together well.
Next, line a baking sheet that can withstand high heat with foil.
Cut a little bit off of the ends of each baguette and then slice each baguette into 12 pieces, or to the preferred size. Set the slices of bread on the baking sheet, leaving some room in between each piece. Spoon out the mixture onto the tops of each piece of bread. (give a generous amount)
Then bake them in the oven until the cheese has melted and the bread feels firm with a nice crisp, about 5-7 minutes. (may vary depending on the baguette)
Serve them warm.
