In a small bowl mix together all of the ingredients for your chive and onion spread.
Reserve until needed.
Lightly toast bread. Once cooled, on one slice spread a thin layer of chive & onion spread.
Top with spinach, cheese, mashed avocado (plus 1 tsp fresh lemon juice & salt to taste), cucumber, tomatoes, and sprouts.
Sprinkle on the sunflower seeds. Spread thin later of chive & onion spread on another slice of bread and top your sandwich. Enjoy!
