Preheat oven to 400 degrees Fahrenheit.

In a medium-sized bowl, combine the tomatoes, onion, garlic, lemon juice, oil, salt, pepper, and pastrami – except for one-third cup pastrami, which should be reserved for garnish. Allow to marinate.

Slice baguettes into half-inch-thick slices and lay on a baking sheet. Lightly spray each slice with oil spray. Bake for seven to 10 minutes or until golden.

In a frying pan, sauté one-third cup pastrami for about five minutes or until crunchy.

To assemble, spoon veggie mixture on top of each slice of bread. Garnish with pastrami and crispy onions.
