This is super easy and good. It would be easy to augment with the addition of sun dried tomatoes, or feta, or use goats cheese instead of cream. Just do whatever strikes you.
1 brick of cream cheese (Neufchatel is great too)
1/2 C. Pesto (pesto’s vary so you might find you want more for a really strong pesto flavor)
1 tsp. lemon juice
1/4 c largely chopped walnuts
Let cream cheese soften. Add all the above. Mix until incorporated. Serve.
Any leftovers would be great in a stuffed chicken breast with some artichoke and feta or kalamatas.
