The Lean Cuisine Philly Style Steak & Cheese Panini features "beef steak, red & green peppers, onions and cheese sauce on sourdough bread." While this can in no way be compared to a real Philly Chesesteak, I think Lean Cuisine does a great job of making a tasty "Philly-style" sandwich.
There was plenty of everything, onions, peppers and strips of beef which was flavorful and tasted like it had been marinated. This is a much better offering than LC's other steak sandwich, Lean Cuisine Steak Cheddar and Mushroom Panini which was a hot mess (read the review).
The Lean Cuisine Philly Style Steak & Cheese Panini has 350 calories, 9 grams of total fat and 4 grams of saturated fat (14 and 20% of the recommended daily amount), 13% of the RDA for cholesterol (40 mg), 30% of the RDA for sodium, 21 grams of protein and 46 grams of total carbohydrate which includes 3 grams of sugar and 3 grams of fiber (12% of the RDA).
A box of this cost $2.85 which is reasonable (and Lean Cuisine goes on sale often), but the nutrition facts of this variety leaves a lot to be desired. Lean Cuisine Chicken Spinach and Mushrooms Panini has 70 fewer calories (read the review) and tastes just as good.
