Preheat oven to 400F / 200C and line a baking sheet with parchment.
Add all the pesto ingredients to a small blender and blitz until smooth. Adjust seasoning and lemon juice to taste. Option to add a touch more olive oil if you like it runnier.
Add tenders to a bowl and toss with ¼ - ⅓ cup of pesto to taste. Wrap each tender in parma ham and place on baking sheet.
Bake for about 15 minutes until the chicken is cooked through and the parma ham crispy. Brush with more pesto to serve and fresh chopped basil.
Any remaining pesto can be stored in a sealed glass jar in the fridge for 5 days.
