no. your $1 choices are, a spicy potato soft taco, which is a tiny tortilla, four potato pieces, a pinch of lettuce, and a dusting of cheese, and there may or may not be some chipotle sauce. most places tend to forget that this is part of it though so ymmv.
a cheesy roll up, which is a tiny tortilla. and cheese. rolled up.
those cinnamon twist things which are just cardboard
and a cheesy bean and rice burrito, which is about the size of a roku remote.
so no, $1 isn't worth anything at taco bell.
and that's if those are even $1. at a lot of taco bells now they're over $1. it's like a problem.
Buying a bunch of them is cheaper than an actual meal.
