I cook most of my food now and trying to lose weight while eating prepackaged meals was a big reason I couldn't stick with a "diet" in the past, because I would just get so freaking tired of eating that unappealing food, but here's some ideas:
peanut butter or tuna for sandwhichs
those starkist or bumblebee lunch kits
fruit, hard cheeses, soup
I have tried most of those meals you mentioned in the past and the best I can say for them is that they were edible.
