Place sunflower seeds (not the type in the shell!!) and 1-3 tablespoons of oil in a high-powered blender or food processor; blend for 1-3 minutes or until nuts turn into a paste. Add additional oil a little at a time until desired consistency is reached.
Spread sunflower butter onto 4 bread slices, drizzle with honey, then top with remaining slices of bread to form 4 sandwiches.
Chop pineapple and slice bell pepper.
Serve sandwiches with pineapple and pepper slices on the side.
