This delicious sumac roasted sweet potato salad with quinoa, feta, chickpeas, baby spinach and toasted walnuts all tossed in a simple lemon dressing is packed with flavour and textures. This nourishing salad is perfect for lunch and will keep you full all afternoon long.

I have been on a quinoa salads quest recently; creating different and nourishing salads that are packed with goodness – and are full of delicious flavours too! These type of salads are ones where you can prep ahead – or prep components of them – and then enjoy throughout the week. Just like this halloumi quinoa salad, these filling salads are delicious in the cooler months too – salad is not just for summer 😉

Ingredient notes and substitutions
Please scroll down to the recipe card at the end of the post for ingredient quantities.
- Sumac – this tart, tangy spice with its beautiful red hue adds a slight citrusy tang to the sweet potato. If you don’t have it then omit it.
- Sweet potato – or substitute with butternut squash or pumpkin.
- Feta – or substitute with goats cheese.
- Chickpeas – I also like to use cooked brown lentils in this salad if I don’t have chickpeas.
- Walnuts – substitute with almonds, or leave out altogether if you want a nut-free salad. The pumpkin seeds / pepitas provide the crunch.

Serving Ideas
This salad is a meal in itself, however it is the perfect side to roasted or grilled meats or fish, or serve with some dips – hummus, yogurt dip, prosciutto and flatbread for a simple lunch with friends.
Make ahead/storage
I recommend serving the salad immediately after mixing together as the spinach can wilt and become watery. However you can make various elements to the salad ahead:
- Roast the sweet potatoes – and store in the fridge, covered, for up to 3 days.
- Toast the walnuts and pumpkin seeds – and store in an airtight container for up to 3-5 days.
- Make the lemon dressing – and store in the jar in the fridge for up to 3 days.
Leftover Ingredients
Food is a huge expense, and unfortunately quite easy to use half a packet here, or a quarter of a bunch there, and then forget about the rest, to have it destined for the bin or compost heap. So here are a few ideas to help use up some of the ingredients you may have leftover once you have made this sweet potato salad.
- Feta – sprinkle over wilted greens or stir fried silverbeet (or substitute spinach); use in this green bean salad or sprinkle over baked eggs.
- Lemon – add any leftover lemon to a chicken traybake or, if you have more than half a lemon, have a look at these lemon recipes.
- Walnuts – store your packet of walnuts in the fridge. Use them to make this pear and walnut salad, walnut dill pesto or coffee and walnut cake.
