One of my favorite parts about summer is the easy side dish options!

In the winter, I feel compelled to make hearty, warm, comforting side dishes like my broccoli cheese casserole or keto cauliflower casserole.

I mean, don’t get me wrong – those are two of my favorite dishes of all time!

I just like making lighter (and easier!) side dishes too! Take my keto broccoli salad and keto cucumber salad! Both are perfect for summer and we just love them!

This keto Greek salad is the perfect light side dish – packed with flavor, delicious served straight from the fridge, light and refreshing, and totally simple!

This recipe starts out with a pile of veggies, so grab a cutting board and a good knife.

Slice 1 English cucumber in half and then into small pieces, to form half moon shapes.

Halve your cherry tomatoes, slice thin slivers of red onion, and dice up a bell pepper.

Add all of these veggies to a mixing bowl along with some kalamatta olives and crumbled or cubed feta cheese.

You may notice that these pictures don’t show the feta cheese! I forgot to add it when I made it to photograph – I don’t know how I possibly forgot to add cheese either, but it happened. 😉 Don’t be like me – add the feta as called for in the ingredients!

To prepare the dressing, you’ll want to whisk together olive oil, red wine vinegar, lemon juice, garlic, dijon mustard, oregano, salt, and pepper.

This is one of those dressings that is positively bursting with flavor!

And yes, it’s delicious on a green salad too!

Pour the dressing over the vegetables and toss to combine.

We like this salad best cold from the fridge, so we usually make this an hour or two in advance.

This also allows the veggies to soak up that delicious dressing and really get flavorful.

You can also serve this Greek cucumber salad at room temperature, if you prefer.

This keto Greek salad will last nicely in the fridge for 4-5 days, depending on how fresh the vegetables were when making the salad.

Store this tightly covered in the refrigerator.
