Preheat the oven to 220C, fan-forced. Line an oven tray with baking paper. Cut the unpeeled sweet potatoes into 2cm-thick rounds (see Make it faster). Cut the cauliflower stem into 1cm chunks, then cut the head into small florets.
Step 2 — Roast veggies
Put the sweet potato on the lined tray, drizzle with 2 tsp vegetable oil, season with salt and pepper and toss to coat. Roast on the top oven shelf for 10 mins. Add the cauliflower to the tray, drizzle with 2 tsp vegetable oil, season with salt and pepper and toss to coat. Roast for a further 15 mins or until the veggies are tender.
Step 3 — Prep ingredients
Meanwhile, crush or finely chop 2 garlic cloves. Trim the beans and cut into 3cm lengths. Juice half the lime and cut the remaining half into wedges. Cut the chicken into 3cm chunks. Drain and rinse the lentils.
Step 4 — Cook curry
Heat 2 tsp vegetable oil in a medium deep frypan over high heat. Cook the chicken, stirring, for 2-3 mins until browned. Reduce the heat to medium. Add the garlic and 1 tbs curry paste* and cook, stirring, for 1 min or until fragrant. Add the coconut milk and 80ml (⅓ cup) water and bring to a simmer. Add the beans and cook for 3 mins or until tender.
Step 5 — Serve up
Stir the lentils and lime juice into the curry and cook for 2 mins or until the chicken is cooked through. Taste, then season with salt and pepper. Divide the sweet potato and cauliflower among bowls and top with the curry. Serve with the lime wedges to squeeze over. Enjoy!
Step 6 — Make it faster
We've cut the sweet potato into thick rounds so it acts as a 'bed' for the curry rather than rice. However, to speed things up, cut it into smaller pieces and roast for the same amount of time as the cauliflower.
