Subway's 'meat' is a processed paste made from factory-farmed chicken, beef, or turkey, mixed with preservatives and seed oils. You're eating a manufactured product, not real meat. This is not food, it's a factory-made imitation.
Why trash
Their 'fresh bread' contains over 40 ingredients. A real loaf needs 4.
Try instead
Grass-fed beef or turkey breast, avocado, lettuce, tomato, cucumber, red onion, mustard.
