Fresh ingredients laid out for a healthy smoothie: Liberté key lime yogurt, Silk vanilla almond milk, bananas, a lime, and frozen broccoli—simple and nutritious.

If you’re familiar with my other posts on eating healthy – like my 3 Quick & Healthy Breakfast Ideas – you know that I’m all about packing in some protein before school drop-off. Smoothies are an easy way to get both those essential fruits, vegetables, and calcium in before you start your day. Sometimes, I even add a splash of cold brew – check out my Coffee Protein Smoothie recipe!

A Classic Summer Treat in a Glass

Key Lime Pie is a classic summer treat. Its zesty tang pairs beautifully with creamy custard and graham cracker crust. If this is what makes the pie so delicious, why wouldn’t a smoothie be the same? In this version, the tangy lime and creamy yogurt take center stage, while the frozen broccoli hides in the background, boosting nutrition without affecting the flavour. Plus, it gives the smoothie that fantastic green colour. Trust me, you (or your kids) won’t even know it’s there!
