Ingredients

1. 1/4 cup mayonnaise
2. 1 1/2 tablespoons ketchup
3. 1/2 teaspoon fresh lemon juice
4. 1/2 teaspoon Worcestershire sauce
5. Tabasco
6. Salt and freshly ground pepper
7. 1/4 cup vegetable oil
8. 1 small onion, thinly sliced
9. 1 small beet, peeled and thinly sliced
10. 2 medium carrots, thinly sliced
11. 1 medium Yukon Gold potato, peeled and thinly sliced
12. 3 large eggs, lightly beaten
13. 4 bialys or bagels, split 

Directions

1. In a small bowl, mix the mayonnaise with the ketchup, lemon juice and Worcestershire sauce. Season the sauce with Tabasco and salt and pepper.
2. In a large nonstick skillet, heat the oil until almost smoking. Add the sliced onion and cook over moderate heat until softened, about 3 minutes. Add the beet slices and cook until almost tender, about 5 minutes. Stir in the carrots and cook for 5 minutes. Add the potato, season with salt and cook until all of the vegetables are tender, about 7 minutes.
3. In a medium bowl, beat the eggs with a dash of Tabasco; season with salt and pepper. Gently stir the eggs into the vegetables, cover and cook over moderate heat until the eggs are just barely set, about 5 minutes. Flip the vegetable omelette with a spatula and cook for 1 minute longer. Transfer the omelette to a work surface, cover loosely with foil and keep warm.
4. Meanwhile, lightly toast the bialys. Spread the sauce on the bialys. Cut the vegetable omelette into 4 wedges, set a wedge on each bialy, close the sandwiches and serve.
