How to Make It
Heat olive oil in a medium saucepan over medium-high. Add onion, and cook, stirring often, until tender, 5 to 6 minutes. Stir in fire-roasted tomatoes, masala seasoning, salt, and cayenne pepper; cook, stirring often, until onions are very soft and tomatoes are beginning to break up and soften, 5 to 6 minutes. Add 2 1/2 cups water; bring mixture to a boil. Add oats; stir until incorporated. Reduce heat to medium; cook, stirring often, until all liquid has been absorbed and oats are tender, 5 to 6 minutes. Add butter; stir until melted.
Divide oat mixture among 4 bowls. Top each evenly with yogurt, chopped trail mix, and cilantro. Serve hot.
