Ah - invaded - so that means by military force. Not many really. Settled in - yes, ruled for a short time - yes, discovered even - yes, but actually militarily invaded and ruled - not many.that's easy. just look at the food of all the countries we have ever invaded and mix them together. problem solved!
Further we do have many old recipes and old traditions but like most things we tend to ignore them or even worse laugh at them eg morris dancers are often a figure of ridicule but to do the same to for example, an African tribal dance would be considered VERY bad taste and it's the same with our cooking.
American food is young but to get back to English food we must go back at least 500 years and the trail is a very tangled one but that does not mean it should simply be forgotten about and dismissed.
PS - apple pie is not really American is it. I could be wrong but, although they do eat it as we do hot dogs etc the apple pie came from - yep - England.
