Preheat oven to 250 degree F. Line a baking sheet pan with non-stick aluminum foil wrap, large enough to be able to tightly wrap the tri-tip roast and vegetables.
On top of the aluminum foil, place onions, bell peppers, and garlic in a line about the size of the roast. Sprinkle vegetables with salt and a few twists of ground pepper.
Generously sprinkle the tri-tip roast with the Montreal Steak Seasoning on all sides; place on top of the vegetables and sprinkle with Ponzu Sauce.
Wrap the aluminum foil tightly around the vegetable/meat mixture to keep the juices from escaping during baking.
Bake approximately 3-1/2 to 4 hours. NOTE: Do not open the oven door and peek at the roast during this time. The odor in your house will be fabulous!
Remove from oven and transfer the meat to a carving board or platter, let it rest for 10 to 15 minutes before carving to allow the residual heat to complete the cooking and the juices to stabilize.
Slice the meat into thin slices across the grain or shred the meat.
Serves many.
Serving Ideas:
The meat can be sliced and served along with the vegetables.
Shred the meat, chop the vegetables, and then mix the shredded meat with the chopped vegetables and juices to use for tacos or burritos.
Ponzu is a soy sauce which is infused with citrus and commonly used in Japanese cuisine. If you can not find this sauce in your local grocery store, use the recipe below and make your own.
Combine all the ingredients in a bowl. Cover and chill until ready to serve.
Makes 1 cup.
