Preheat oven to 450°; heat 1 tbsp oil in skillet over med-high + cook 4 tenders 2-3 min per side until crispy + hot

Transfer tenders to a lightly oiled sheet pan + top each tender with 2 tbsp sauce + 2 tbsp cheese; bake 4-5 min

Meanwhile, heat 1 tbsp oil in large skillet over med-high + sauté half the spinach + salt/pep, 1-2 min until wilted; add remaining spinach + cook 1-2 min more until all spinach is wilted

Toast 2 buns until golden + add 2 tenders to each bun; serve spinach on the side—looks great!
