Sweet Potato Sandwich with Vegan Tzatziki Sauce

This sandwich is packed with the power of sweet potatoes, and finished off with a tasty vegan tzatziki sauce. Each ingredient has been selected to help you along with your detox and make you feel great.

Sweet potatoes are my latest obsession! I am totally in love with its taste, and I use it in almost everything –from smoothies and juices, to salads and curries. I especially like it roasted with coconut oil, which reveals its rich, creamy texture and sweet taste. Today I wanted to make a quick but nourishing sandwich to go, but I didn’t have too many ingredients in my fridge.

You might not think these would fit into a sandwich, but the roasted sweet potato rounds I made for a salad the evening before were the only thing I had available, so I had to give it a try. And the whole wheat bread, zingy vegan tzatziki and greens made the perfect pairing!

There are many things to say about the nutritional power of sweet potatoes, but I think these are the most important to have in mind when considering sweet potatoes for your detox diet: their antioxidants, potassium, and beta-Carotene content.

The bright orange color (sometimes purple) is a sign of the beta-Carotene it contains. Sweet potatoes not only contain high amounts of beta-Carotene, but also antocyanin antioxidants. These lower the potential health risk from heavy metal accumulation (like mercury, cadmium or arsenic) and are a great help against the process of oxidation from free radicals.

Potassium is a key mineral when it comes to the natural detox function of our bodies. Found in high quantities in sweet potatoes, potassium helps the body’s cells to keep sodium levels where they should be, an important factor to consider when detoxing the body.

The best way to cook sweet potatoes is to steam or roast them. Simmering causes the loss of potassium into the boiling water, and it’s not a recommended cooking method unless you’re making a soup. Roasting is my favorite cooking method because I love the sweet taste and moist texture of sweet potatoes cooked this way. I simply add a little bit of coconut oil, some salt, and freshly ground black pepper and roast them for 15-20 minutes in the oven.

This sandwich called for a sauce, and there’s nothing easier than making vegan tzatziki. I always have soaked seeds in my kitchen because I use them for preparing vegan milks and for snacking. This vegan tzatziki is made out of soaked seeds, lemon, cucumber and parsley and it’s simply delicious. You can use it for assembling veggie sandwiches and burgers, or as salad dressing. Its fresh, has a zing to it, and comes with a creamy texture!
