Step 1

Preheat oven to 350 degrees Fahrenheit. Grease an 9 inch square baking dish or line with parchment paper, which I recommend for easy removal.

Step 2

Heat oil in a skillet over medium heat. Add all the vegetables and cook for 4-5 minutes, or until softened. Add Italian seasoning and tomato paste and cook for a couple of minutes, stirring so everything gets well incorporated. Remove from heat and set aside to cool slightly.

Step 3

In a large bowl, combine the rest of the ingredients. Add the vegetables. Let mixture sit for 5-10 minutes to allow for the oats to soften.

Step 4

Pour into the prepared baking dish and press mixture evenly.

Step 5

Bake for 30 minutes, until all liquid has been absorbed and oats are set and firm to touch. Be sure to cool before slicing for a clean cut.
