This couscous salad is my go-to for quick lunches and vibrant summer dinners because it brings together sweet potatoes, black beans, baby spinach, and feta under a zesty lime basil vinaigrette. Every bowl feels wholesome and satisfying, but the real magic is how the flavors layer and complement each other, making this salad crave-worthy any time of year.
Once I made this for a last-minute picnic It was such a hit that even the pickiest eaters asked for seconds and the vinaigrette is now on regular rotation in my kitchen

Step-by-Step Instructions
- Cook the Couscous:
- Bring water to a gentle boil Stir in couscous cover and remove from heat Let stand for about five minutes Once the water is absorbed fluff with a fork so each grain stays separate Cool to room temperature so the salad is light not mushy
- Roast the Sweet Potatoes:
- Peel and dice sweet potatoes into small cubes Heat them in a skillet with a splash of water and a pinch of salt Cover and let them steam over medium heat until fork tender about ten to twelve minutes Drain any remaining water and let the potatoes cool This method ensures they become melt-in-your-mouth soft
- Make the Lime Basil Vinaigrette:
- Add fresh basil olive oil lime juice garlic salt red pepper flakes and just enough water to a food processor Blend until nearly smooth Taste and adjust lime or salt to preference The dressing should be punchy but balanced If too thick add a splash more water
- Chop and Prep Vegetables:
- Rinse and cut baby spinach into bite-sized pieces Slice red onion thinly so it blends without overpowering the salad If using pistachios chop them roughly for extra crunch
- Assemble the Salad:
- In a large bowl combine cooled couscous sweet potatoes black beans spinach feta and onions Pour over the vinaigrette Toss gently but thoroughly so every bite shines with flavor Add pistachios and finish with black pepper Taste and add more lime or salt if desired
- Serve or Store:
- Serve immediately for a warm tangy treat or refrigerate and enjoy chilled throughout the week For meal prep keep each element separate and build fresh salads as needed

I have a soft spot for feta in any salad but in this recipe its creaminess pairs especially well with sweet potatoes My sister once called this vinaigrette life-changing at a family barbecue and now no one lets me show up without it
Storage Tips
Store leftovers in an airtight container in the fridge for up to three days The salad holds up well and the flavors meld beautifully over time but for ultimate freshness keep the dressing separate until just before serving If prepping ahead do not add the spinach until the last minute to prevent wilting
Ingredient Substitutions
If you are out of sweet potatoes try butternut squash or carrots Swap black beans for chickpeas or cannellini Add kale or arugula if spinach is unavailable Goat cheese or a dairy-free cheese works in place of feta Any soft green herb can substitute for basil though the flavor will shift in the vinaigrette
