Preheat your oven to 475º degrees Fahrenheit. Peel, rinse and cut the potatoes into small, even strips then place into a bowl of hot tap water for at least 15 minutes. Slice the peppers into 2" -inch strips. Slice the onion vertically. Core and cut each tomato into 8 wedges. Thinly slice the beef against the grain into bite-sized pieces.
Drain the potatoes and pat dry. Toss the potatoes with about one tablespoon of the oil. Season well with salt and pepper and toss again. Oil a baking tray with 3 or 4 tablespoons of the oil. Lift the potatoes out of the bowl and place onto the baking tray. Arrange them in a single layer, wrap with foil, and place into the oven. Bake for approximately 10 minutes.
