Preheat oven to 350 degrees F.
Slice tofu block lengthwise into six 1 inch slices. Do not cut it widthwise into squares slices. You want rectangle slices.
With a small biscuit cutter, cut sliced tofu into rounds.
Brush tofu rounds on both sides liberally with lemon vinaigrette and place on a baking sheet.
Bake for 35-45 mins, turning once, until slighlty browned and firm, chewy consistancy of cooked egg white.
Once done, remove from oven and let cool on a rack.
Prepare the "yolk": Place the avocado into a food processor with the mayonnaise, salt free seasonings of your choice, onion powder, garlic powder, epper, and nutritional yeast. Blend well, scrapping down the sides occasionally until smooth and creamy.
Preparing eggs: Once tofu rounds are cool, place on a serving tray. Scoop or pipe a half teaspoon of the avocado mixture onto the center of each round.
Garnish each with a sprinkle of paprika and some chopped chives
Chill until serving.
