Assuming Steve needs 7,000 kcal per day, that would equate to 3.5kg/8lb of sausages per day.
Good thing that's not all he eats!
“Hello, Steven, teatime! Sausages for tea! - Steven! Steven! Come on, son. Sausages for tea! Fresh Sausages!"
"Oh, I don't want Sausages for tea, Daddy."
"What? I went out specially and got them for you."
"Aw, but Daddy, we had Sausages yesterday."
"Look, son, I walked seven miles to the High Wood to get you Sausages. That's fourteen miles in all, counting the journey back, and you don't want Sausages? I fried them for you. Fried Sausages - mm - I fried them in butter."
"I don't want them, Daddy. Daddy, we've had Sausages for three years now. I'm fed up with Sausages. I don't want them any more. Daddy, can't we have something else for tea?"
"Oh, son! Sausages! They're lovely."
"Daddy, I don't want Sausages any more. I hate Sausages. I detest them. I have them every day and they're always fried in butter. Can't you think of another way of cooking Sausages? There's hundreds of ways of cooking Sausages: boil them or bake them or stew them or braise them - but every day - fried Sausages. 'Steven, come in for tea. Fried Sausages. I've walked fourteen miles. Seven miles to the High Wood and back.' Three years of Sausages. Look what it's done to me, Daddy! Come here! Come here into the bedroom and look at ourselves in the mirror, you and me. Now look at that!"
"Yes. I see what you mean. Son, let's not waste these Sausages. Tomorrow, I'll go to the High Wood and get something else."
"Look, Daddy, you've been saying this for three years now. Every day we have this same thing. I take you to the mirror and you say we'll have something else for tea. What else is there in the High Wood besides Sausages?"
"Well, there's leaves, bark, grass, and leaves. Sausages are really the best. You must admit it."
"Yes, Daddy, I admit it. Sausages are really the best, but I don't want them. I hate them. I detest them. In fact I'm going to take this panful of Sausages and throw them out."
"Oh, don't do that! Don't throw them out for goodness' sake! You'll poison the dog!"
