Ingredient Highlights
- Lamb’s lettuce: Soft, slightly nutty, and rich in vitamins—perfect as a delicate base for hearty toppings.
- Tuna: A lean, high-protein ingredient that adds substance and keeps the salad satisfying.
- Baked sweet potato: Comforting, naturally sweet, and full of fiber and complex carbs.
- Roasted beans: Crispy on the outside, tender on the inside. They’re great for plant protein and texture.
- Sunflower & pumpkin seeds: Crunchy, nutrient-dense, and packed with healthy fats and minerals.
- High-protein yogurt dressing: Creamy, tangy, and light, bringing everything together without weighing the salad down.
Tips, Tricks & Common Mistakes
- Roast everything properly: Let the sweet potatoes and beans caramelize slightly, which wil add depth and flavor.
- Don’t overdress: Add the yogurt dressing gradually so the salad stays fresh and balanced.
- Use contrast: Warm toppings + cool greens + crunchy seeds = a perfect bite every time.
- Meal-prep friendly: Store dressing separately and assemble just before eating for best texture.
Variations & Customizations
- Vegan version: Skip the tuna and use a non-dairy high-protein yogurt alternative for the dressing. You can add extra beans or chickpeas for some extra protein.
- Extra protein boost: Add a second plant protein or a soft-boiled egg if desired.
- Seasonal twist: Swap sweet potato for roasted squash or beets depending on the season.
- Leafy greens: Instead of lamb’s lettuce you can always use other leafy greens like arugula, spinach or green lettuce.
Golden Sweet Potato and Tuna Winter Salad
Equipment
- 2 Baking tray
- 1 Salad bowl
- 1 Oven
Ingredients
- 4 cup lamb's lettuce 100 g
- 10 oz canned tuna 2 cans, 140 g
- 3 sweet potatoes medium-sized
- 2/3 cup cooked brown beans 100 g
- 1/4 cup pumpkin seeds
- 2 tbsp sunflower seeds
- 4-5 tbsp skyr or low-fat Greek yogurt 70-85 g
- 2 tbsp extra virgin olive oil
- 2 tbsp apple cider vinegar
- 1/2 tbsp chopped/crushed chives
- salt
- pepper
- garlic powder
- rosemary
- thyme
Instructions
- Preheat the oven to 355o F (180 o C)
- Wash, peel and cut the sweet potatoes into long, fries-like pieces. Place them on a baking paper covered baking tray, drizzle with olive oil and season as you like. I used salt, pepper, rosemary and thyme. Bake for about 30-45 minutes, until they are fork tender on the inside and golden/brownish on the outside.
- While the potatoes bake, combine the beans, sunflower seeds and pumpkin seeds in a bowl. Drizzle with olive oil and add a pinch of salt and ½ tsp of garlic powder. Mix to make sure they are evenly covered. Place them on a baking tray and let them roast in the oven for about 20 minutes. The beans should pop and look very crispy.
- In the meantime prepare the high-protein yogurt dressing. Combine 4 tbsps of low fat greek yogurt or skyr, 1 tbsp olive oil, 2 tbsp apple cider vinegar (or lemon juice), 1 tsp garlic powder, ½ tsp salt and ½ tbsp freshly chopped or dried chives. Mix well to combine. Make sure you test it and add anything to taste.
- Assemble the salad; Wash and dry the lamb’s lettuce and add it to a large serving bowl. Layer the tuna, sweet potato, beans and seeds over it.
- Drizzle with the creamy high-protein yogurt dressing just before serving. Add salt to taste.
- Toss gently and enjoy immediately.
