You need to be eating fat:protein:carbs.
Here's what I'd do with your day:
Breakfast
2 eggs
Sausage
Probably replace the sausage with bacon, as there will be fewer carbs, but also wouldn't have this everyday because it's processed. Eggs on their own are fine. How about some mushrooms with them?
Lunch
Few slices ham
Again, processed meat. Try going for some cooked chicken, or tuna, and have some salad with this, with an oily dressing and/or some vinaigrette
Dinner
2 sausages/tin tuna mayo
Leaf spinach.
More processed meat, and do you know the carb count of the sausages? I'd suggest fresh meat/fish, fried in butter/lard/coconut oil, or a roast of some kind - belly pork would be fab as it's nice and fatty - with broccoli or cauliflower or courgettes, and some salad. Lots of butter on your veg, even a creamy/cheesy sauce (not made with flour). Or roast veg, done in lots of olive oil - aubergine, courgettes, leeks and shallots is a nice combination
