I'm a big fan of guacamole. It never seems worth the cost to buy the avocados full-price at the market: I usually have to let the rock-hard grenades ripen for a while before I can use them. Plus, if I wait a bit, Kroger will put reduced-price avocados out, typically 99 cents for a bag of 5 or 6 of them. They'll be overly ripe, but there will be plenty of good green flesh for my guacamole needs.
Guacamole is a blend of avocados, onions, peppers, lime juice, cilantro, and other seasonings....the avocado is a blank canvas, more or less, the way that plain mayo gets blended with hot sauce to make a spicy mayo.
And, as with spicy mayo, guacamole isn't something I have by itself. It's always an accessory to burritos, tacos, and chips.
I suppose, in this case, asking if I like avocados is a bit like asking if I like plain pasta with nothing on it, or plain chips with no dip. There's just not enough there for it to hold my interest.
Now, about avocado toast. Just plain avocado on toast is mildly interesting to me. I find that I'll take a bite, think about it for a moment, then want to add something to complete the flavor of the next bite. There's just not enough there to hold my interest. Guacamole toast? Sure. But, if I'm doing that, I'll want to get another piece of toast, and slide some meats and other vegetables between them. And, if I'm doing that, I might as well just make a burrito or a taco.
