Combine all ingredients except oil and tofu in a food processor and blend, slowly adding the oil until the mixture is smooth.
Cut the tofu into slices 1 inch thick and dip them into the mixture until coated, reserving some of the mixture.
Lay the tofu on a baking sheet and broil for 10 minutes, then flip to the other side and coat with the remaining mixture.
Sprinkle with sesame seeds and chopped green onions before serving.
