Slice the bread, brush with olive oil and garlic salt, and bake in oven until lightly toasted. Meanwhile, grill the sausage and prepare the tomatoes as follows:
Heat 1 tablespoon olive oil in a large sauté pan. Add garlic, onion and fennel seeds and sauté lightly, about 2 minutes. Add tomatoes and remove from heat.
Top bread slices with the tomato mixture and serve with sliced chorizo sausage.
Garnish with roasted red pepper strips.
