In a mixing bowl, combine 1/4 cup of PB2 (or your choice of powdered peanut butter) with 2 tablespoons of unsweetened vanilla almond milk. Add stevia to taste, mixing until smooth and creamy. Set aside.
In another bowl, whisk together the liquid egg whites, 1/2 cup almond milk, 1/4 teaspoon vanilla extract, 1/4 teaspoon cinnamon, a pinch of salt, and stevia to taste until well combined.
Take a slice of whole wheat bread and spread a generous layer of the peanut butter filling on one side. Spread about 1 tablespoon of sugar-free strawberry jam on top of the peanut butter. Place another slice of bread on top, creating a sandwich. Repeat with the remaining slices.
Preheat a non-stick skillet or griddle over medium heat. Lightly spray with cooking spray if needed.
Carefully dip each sandwich into the egg white mixture, ensuring both sides are coated. Place the coated sandwiches onto the skillet. Cook for about 3-4 minutes on each side or until golden brown.
Remove the French toast from the skillet and serve warm. Drizzle with more sugar-free strawberry jam or enjoy as is!
