Place a large saucepan of water over high heat and add the stock powder. Once boiling, add the risoni and cook according to packet instructions (8 minutes). Around 2 minutes before draining the risoni, add the asparagus to the boiling water. After 2 minutes, remove the asparagus with tongs. Drain the risoni and run under cold water. Roughly chop the asparagus. Set both aside.
Marinate the chicken tenderloins in the olive oil and dried oregano. Mix and season well. Place a large frying pan over medium–high heat and cook the tenderloins for about 5 minutes each side (depending on their size). Remove and set aside.
For the dressing: Mix all the ingredients in a bowl or jug and season well. Adjust to taste.
2 tablespoons extra virgin olive oil, 1 lemon, 1 teaspoon dijon mustard, 1 teaspoon pure maple syrup
Place the risoni, asparagus, cherry tomatoes, cucumber, red onion, mint, feta and pine nuts in a large bowl. Drizzle over the dressing and toss together. Season well. Top with the chicken tenderloins and squeeze over some fresh lemon juice before serving.
