Mexican in Portland?
For what you like, you might enjoy Esparza's for Tex-Mex. Not sure about the cubes, but their food can be spicy and the enhilada sauce should be plentiful. If you're ever in Raleigh Hills, Si Senor in the Fred Meyer lot is a very nice selection that belies its shopping center locale. df, Tac. Nueve, and Nuestra Cuc. are all great and popular, but may all be a little too upscale to give you the enchilada sauce you're looking for.
