Dried herbs are available just like you'd buy for home. I'm not good at selecting which ones without following a recipe. I'll be trying what the others have suggested.
I've tried a few packaged seasoning mixes. I bought the envelopes intended for a single dish. Here is what I've tried.
McCormick Italian herb baked chicken and pasta.
McCormick chicken taco
Great Value (Walmart brand) mild chili seasoning mix
Goya Sazon
The Sazon was a complete waste of money based on the 2 times I tried it. I can barely tell a difference in taste with or without it. It mostly changed the color of the rice.
All of the other seasonings worked great. I use 1/2 the envelop each time and just needed a dash of salt.
