Hi,
It's hard to say as we eat all types of food here and lots of people don't just stick to 'English' food but enjoy all sorts. The examples you give are what we call a roast dinner and these are usually saved for Sundays. (You'd get pretty fat if you ate like that all week!)
Roast dinners - examples
Lamb with mint sauce/roast beef/roast pork with crackling (crispy skin) and apple sauce/roast chicken. One of these would be served with Yorkshire puddings, roast potatoes, and vegetables.
Other traditional English dinners
Toad in the hole - sausages baked in a large Yorkshire pudding.
Beef stew/casserole - lots of variations on this
Shepherds/cottage pie. Minced lamb (shepherds) or beef (cottage) in gravy baked in the oven with mashed potato on top.
Most people eat quite a lot of chips too. I try to stick to once a week or so but I grew up eating them probably 3 or 4 times a week. Meals like egg and chips, sausages and chips, chop and chips are very common.
But if you want to know what I really ate over the last week for dinner:
Thursday - spaghetti carbonara with mixed salad
Wenesday - cottage pie with brocolli, carrots and mixed fried onions/leeks
Tuesday - vegetable rice (onion, orange pepper, carrot, brocolli) with pork chop
Monday - caesar salad, and southern fried chicken pieces
Sunday - shared chinese takeaway (egg fried rice, pork chow mein, prawn crackers, lamb in black pepper sauce, lemon chicken)
Saturday - bacon, egg and chips with peas
Friday - fried trout (a freshwater fish), cheese and chive mashed potato, sweetcorn, asparagus, carrots.
