Start by mashing the ripe avocado in a small bowl until smooth and creamy, which should take about 2 minutes.

Grab your whole wheat bread and spread a generous layer of the mashed avocado on one slice, ensuring it covers the entire surface.

Lay down two slices of tomato atop the avocado, followed by even layers of red onion and cucumber.

Pile on the fresh sprouts evenly over the cucumber slices.

Carefully place the second slice of whole wheat bread on top and press it down gently to hold everything in place.

If enjoying immediately, slice the sandwich in half for easy handling. If preparing for later, wrap the components separately.
