Food is uncountable in one meaning, but in this case food can also mean a dish (type of meal), which in this case is countable.
The second sentence is correct, since you are talking about two separate foods, making plural.
I assume you are counting fried chicken and lamb chop as separate meals.
If you had a dish that consisted of fried chicken and lamb chop mixed together in one meal, then the first sentence would be correct, since you are talking about a singular food (dish). I doubt that this is the case, though.
