To make vinaigrette, combine all ingredients in blender and puree until smooth. Set aside.
Heat olive oil over medium-high heat; add tofu and stir-fry until brown on all sides. Remove to a plate and allow to cool.
Once tofu is cool, combine all salad ingredients except the tortilla chips. Right before serving, toss in vinaigrette. Serve with tortilla chips (they were great crumbled over the top like croutons!).
