Ingredients and Substitutions
- Sweet Potatoes - are highly nutritious and used here for their bright colour and sweet flavour. Roasted to perfection, they bring a mellow sweetness, contrasting beautifully with the earthy lentils. They can be replaced with carrots or your favourite pumpkin variety.
- Lentils - to add some vegetable protein and iron (a cup of lentils provides 6.6mg of iron). You can use brown, green, or even black varieties, aiming for a firm texture. Or replace them with any of your favourite legumes such as chickpeas or black beans.
- Avocado - full of healthy fats it adds a creamy richness and increases the satiety of this salad. If you are not a fan then you can leave it out or replace it with your favourite nuts or soft cheese such as goat's cheese, feta or bocconcini.
- Red Capsicum/Pepper - introduces a crisp, colourful snap, with any bell pepper variety doing the trick or add your favourite hot chilli peppers for some heat.
- Red Onion is used - for its bright purple colour and mild astringent flavour. It can be replaced by any onions you have on hand or you can just leave them out if you don't like them.
- Coriander/Cilantro - Vibrant cilantro ties all flavours together, but if that's not your herb of choice, parsley offers a fresh alternative.
- Cajun Vinaigrette - we have used a flavourful Cajun vinaigrette to add some aromatic flavour to our lentil sweet potato salad but you if you are in a hurry just add some balsamic dressing instead.
Step-by-Step Instructions
Step 1 - Roast Sweet Potatoes
First, preheat your oven to a cozy 180°C/356°F.
Take your sweet potatoes wash them and give them a good scrub, peel them if you like and cut them into small, bite-sized pieces.
It's all about the roast, so toss them onto a baking sheet. Drizzle with 3 tablespoons of golden extra virgin olive oil, sprinkle with 1 ½ teaspoons of Cajun spice and some sea salt then give them a good mix. Make sure they're well-coated.
Into the oven they go for about 30 minutes. You're looking for tender and slightly caramelized edges. Keep an eye out; it's quite the transformation.
Step 2 - Cook the Lentils
While the sweet potatoes are doing their dance in the oven, let’s tackle the lentils. If you've chosen to start from scratch, rinse those lentils first.
In a medium pot, cover them with water, season with some sea salt and bring to a boil. Simmer gently. This is the part where patience is a virtue. About 20-25 minutes later, they should be tender yet firm. Drain them.
You'll find step-by-step prepping and cooking instructions for lentils in our post for black lentil salad.
Step 3 - Prep the Vegetables
Now, give your capsicum and red onion a nice wash. Then, get rid of the core from the capsicum and the papery skin from the onion. Once that's done, chop them up into a small dice, easy peasy 😊.
Next up is prepping the avocados. Start by rinsing and peeling them, then removing the pit and cutting them into medium-sized chunks. Check out our step-by-step avocado prep post for more details!
Don't forget to give your coriander a good wash, and make sure to shake off any excess water. After that, give the stems and leaves a rough chop, and you're all set to add some delicious flavour to your dish!
Step 4- Shake-up the Vinaigrette
In a small glass jar, add the olive oil, red wine vinegar, balsamic glaze, Cajun spice, and minced garlic. It’s all about balance here, then give everything a good shake until it is well combined.
Step 5- Assemble the Salad
Next comes the assembly, the part where everything comes together. In a large mixing bowl, introduce the roasted sweet potatoes to the cooked lentils, add all the chopped veg to the mix then our coriander is next. It adds that fresh, herbal note that wakes everything up.
Drizzle the vinaigrette over the salad and toss gently; you want to keep those textures. You're not just mixing; you're getting all those flavours to know each other.
Arrange in a white salad bowl or platter to really make those colours pop.
You can serve this delectable salad on its own or as a hearty side. It's a versatile dish, perfect for any occasion, promising a burst of flavours and nutrients in every forkful.
