Blend protein powder, spinach, oats, and a banana when you're short on time before the gym. You won't taste the spinach but you'll feel the energy.
Add the almond milk to the blender first to promote smoother blending and prevent dry ingredients from sticking.
Follow by adding vanilla protein powder, rolled oats, and fresh spinach, layering them so heavy items push greens down.
Peel and break the banana into chunks, adding it next for creaminess and natural sweetness.
Top with honey and ice cubes; if you prefer a colder, thicker smoothie, increase the ice, but don’t exceed the blender's max fill line.
Blend on high for 45-60 seconds, pausing halfway to scrape down sides if necessary, until the mixture is completely smooth; serve immediately to preserve the fresh green color and silky texture.
