Begin by toasting your bread. While toasting, make your scallion cream cheese by mixing the scallions in with the softened cream cheese. Add a fresh crack of pepper.
Slice the bell pepper, onion, tomato and avocado in long, thin slices.
When your bread is toasted, add a generous amount of the cream cheese on both sides. Assemble your sandwich by putting the spinach and avocado on one side. Fill the other side with bell pepper, onion and tomato. Add salt and pepper to taste. Smash them together and enjoy!
