Economically speaking, the above mentioned alternatives are the best substitutes for a beef steak.
Explanation:
Substitute is something which can be used in place of another thing. So if some desired thing is not available or is beyond our capacity, then we move towards the substitutes to fulfill our needs of that product.
When economically speaking, taking a substitute is to save some money actually. So if we talk about substituting the beef stake due to increased price of beef in the last few months from 2.31 dollars to 3.86 dollars a pound, then Canned Salmon or Turkey is a best alternative or substitute for beef. They are equally healthy, nutritious, and tasty, and are much lesser in price than Beef.
