Make the Dipping Sauce: Mix all the ingredients in a small bowl. Taste and adjust accordingly.
For the summer rolls: Combine all the veggies and herbs in a bowl and keep ready. Chop tofu into 1-2" pieces and set aside.
In a pie plate or other shallow bowl/ plate, take hot water. Dip each spring roll wrapper in the water for about 3-5 seconds. Remove and place it on a clean work surface or kitchen towel or a plate. Place a handful of the veggie filling on the lower half of the spring roll, top it with the chopped tofu pieces and drizzle some dipping sauce on top.
Cover the filling with the wrapper that is closest to you (bottom of the wrapper), then fold the sides over like an envelope. Finally roll from bottom to top into a cigar shaped tight roll. Repeat with the rest of the rolls.
