Spoon the lentil mixture onto a serving plate and top with the roast squash and red pepper sauce. Dot the goats’ cheese over the top and garnish with the lemon zest. Serve immediately.
Green peppercorns are gentler than black peppercorns, which tend to give a spicy edge to peppercorn sauce. If you want a creamer pepper sauce with your steak this is a great recipe to try.
