Place rack in top third of oven, add sheet pan + preheat oven to 475°; peel (or don't peel!) potato, cut into ¼-½-inch sticks, mix with 2 tbsp oil + salt/pep; carefully remove hot pan from oven, spread fries onto pan + bake 15 min; flip fries over, reduce heat to 425° + bake 10-15 min more until golden

Meanwhile, heat lightly oiled skillet over med-high; pat chicken breasts dry + sear 2 min per side until warmed through

Toast 2 croissants until warm + golden; spread each croissant with 1-2 tbsp pesto

Add chicken to croissants + any tasty extras; serve fries on the side, yum!
