How to Make It
Cut tomatoes into 1/2-inch-thick pieces; place on a plate, and season with 1 teaspoon kosher salt and 1/2 teaspoon black pepper. Set aside.
Combine ricotta, 3/4 teaspoon kosher salt, and remaining 1/8 teaspoon black pepper in a food processor. Process until smooth and light, about 30 seconds.
Toss together peppers and 1 tablespoon garlic oil. Brush both sides of bread slices with remaining 3 tablespoons garlic oil.
Preheat grill to high (450°F to 500°F). Place peppers on oiled grates; grill, uncovered, turning often, until speckled with char, about 3 minutes. Place bread on grill, and grill, uncovered, until well toasted, about 1 minute and 30 seconds per side. Remove any charred, thick skin from peppers. Season with remaining 1/8 teaspoon kosher salt; cut into bite-size pieces, and set aside.
To assemble toasts, spread about 2 tablespoons ricotta mixture on each bread slice. Divide tomatoes and peppers evenly among toasts; sprinkle with flaky sea salt and fennel pollen. Top toasts with basil, chives, a squeeze of lemon, and, if desired, a dash of hot sauce. Serve immediately.
