Alternative to bivariate Taylor series

Is there any expansion to log(1+exp(x-y)) other than
Taylor series in the integer powers of x and y ? 

I'm trying to find expectation of above function given
x, y are random variables with gaussian distributions
of known  mean and variances.

What about other bivariate expansions in Mathematica?
