Heat an oven to 400˚F. Place the torn or cut bread on a sheet tray and pop in the oven. Cook until the bread is crisp throughout and golden; 15 minutes or so. Core the tomatoes and cut into 1” or so pieces. Place in a bowl and set aside.
In a food processor or blender, combine the ingredients for the pesto. Pulse/blend until combined; adding more olive oil or a splash of water as needed to thin well enough to blend. Measure out about ⅓ cup of the pesto and save the rest to use in another meal.
Heat a skillet over medium heat. Add the olive oil, chickpeas, and garlic. Cook until the garlic is fragrant and the chickpeas are hot; 3 to 4 minutes.
Combine the croutons with the tomatoes, pesto, and garlicky chickpeas. Toss until well combined. Taste and add more salt if desired.
