Preheat the oven to 325 °F. Lightly grease a baking sheet

Put a skillet over medium heat and when it is hot, add the oil. Add the onion, bell pepper, garlic, and thyme and cook about 10 minutes until golden.

Lower the heat and add the water and tomato paste. Cook about 10 minutes until the onion is soft and most of the liquid has been absorbed. Set aside to cool. Add the mustard, salt and pepper.

While the onion mixture is cool, put the ground beef, 4 tablespoons rolled oats and the egg in the bowl and gently mix, by hand.

Add the cooled onion mixture and gently mix again until everything is thoroughly incorporated. Do not over mix.

Form the mixture into a loaf about 8x4 inches and put on the prepared baking sheet.

To make the glaze: Put the tomato paste and mustard in a small bowl and mix well. Rub on top of the meatloaf and sprinkle with the remaining 2 tablespoons rolled oats.

Put in the oven to cook about 1 hour until deep brown and cooked throughout. Serve right away or cover and refrigerate up to 2 days.

When using ground turkey add an extra egg
