Choriço is more chile or paprika seasoned than linguica, but the consistency and style are similar, at least compared with the Mexican stuff, which is almost like a meat-based chile paste in a casing.

I grew up in SoCalif, and learned about chorizo when it was virtually unknown among non-Mexicans. You can imagine my surprise the first time I ordered a dish on the east coast that listed chorizo. This would've been back in the 80s in NYC or NJ or thereabouts, when real Mexican food was still largely unavailable.

What I got was delicious, but I knew nothing about the Portuguese stuff, so it was a surprise. I still regard it as one of my best early educational travel experiences

Which reminds me. Another breakfast "sandwich" I love is a machaca con huevos burrito. Yum.
