Gather all ingredients before starting the recipe.
Preheat oven to 350° F
Line a 9x5 loaf pan with aluminum foil letting ends generously hang over sides.
Lightly stretch 1 lb lightly salted thin sliced bacon lengthwise and line the loaf pan, slightly overlapping, then hang 3-4 slices of bacon at each end to overhang by quite a bit, these pieces will be used to cover the terrine.
Heat 1 1/2 tsp olive oil in a medium sauce pan over medium heat and sauté 1/2 cup finely chopped onion and 1 clove garlic, crushed for 3-4 minutes; do not allow garlic to color.
Place of fresh white bread in a food processor and pulse until the bread becomes bread crumbs.
Remove onion and garlic mixture from heat and allow to cool.
Place 12 oz ground veal and 12 oz ground pork in a bowl and add cooled onion and garlic mixture, 1 tbsp thyme minced, 1/4 cup chopped parsley , 1 whole egg the bread crumbs from 3 slices fresh bread , 3/4 tsp kosher salt, 1/2 cup shelled pistachio, 1/2 cup dried cherries or cranberries and 1/2 tsp ground pepper. Mix well using a kneading motion with your hands.
Cut 1 chicken breast into 6-8 one inch strips, about the same width as chicken tenders (or just use chicken tenders).
Bring up the short ends of the bacon and then cover these with the bacon at the ends.
Spread about 1/3 of the minced meat mixture in the loaf pan, arrange 3-4 strips of chicken on top, repeat and end with minced meat mixture on top.
Cover with foil and place in a deep pan. Fill pan with enough boiling water to come half way up the sides of the loaf pan.
Bake for 2 hours; the terrine should feel firm to the touch and the juices should be largely clear
Remove loaf pan from water and cool on a rack for 30 minutes.
Place loaf pan on a tray and cut out a piece of cardboard that fits just inside the loaf pan. Cover the cardboard with aluminum foil and place the 'lid' on the terrine and weigh down with a couple of heavy cans such as beans and refrigerate overnight.
The next day, remove the terrine from the loaf pan, using the foil to help lift the terrine from pan; peel the foil off the terrine and gently scrape off fat and gelled juices from the loaf.
Cut terrine into 1" slices.
Terrine will keep for a couple of weeks in the fridge, or will freeze for several months.
