Place garlic, cilantro, parsley or mint, chickpeas, and bread crumbs in the bowl of a food processor. Pulse a few times to chop and blend ingredients.
Sprinkle 1 tablespoon lemon juice over chickpea mixture and pulse a few more times. Sprinkle baking powder, cumin, salt, Tabasco, and black pepper over mixture and pulse until the chickpea mixture reaches a workable paste-like consistency. Add an additional tablespoon of lemon juice if it seems very dry.
Preheat oven to 400 degrees F. While the oven is getting hot, line a baking pan with foil and brush with olive oil. Using a large tablespoon or #40 disher (ice cream scoop), scoop balls of dough into your palms and form them into patties. Set aside on work surface while you form the remaining mixture.
Arrange falafel patties on oiled baking sheet and brush them with olive oil. Bake at 400 degrees F for about 15 to 20 minutes, until the tops are golden brown and crispy. Turn once midway through baking.
Remove from oven and let falafel cool on pan for a minute or two before removing to plates or pitas with a spatula.
Serve in a whole-grain pita with leaf lettuce and plenty of Tzatziki Sauce.
Combine all Tzatziki Sauce ingredients in a small mixing bowl; stir to incorporate. Cover and chill for at least 30 minutes prior to serving. Taste after chilling and adjust seasonings if necessary.
