Do you like tofu and just weren't happy with how it turned out in that dish? Or are you trying to eat tofu because you think you ought to, because, after all, if you're vegan or vegetarian it's a fundamental requirement to eat tofu and lentils? ;-) If it's the latter, don't force yourself - it's entirely optional. Eat foods you do like.
If you just didn't like how it came out, well, there are many different things you could consider, including the suggestions already made. I don't much care for the taste of tofu in stir fry unless I've marinated it first for at least six hours in something. I have to admit that I cheat and sometimes buy the pre-fried tofu cubes (yeah, nutritionally naughty) as they absorb sauces better without marinating. In stir fries, I prefer the texture of tofu after it's been frozen - it gets harder and chewier instead of just squishy. And sometimes I'll fry it up in oil first (yes, again, not healthy). I usually don't bother with tofu, though. I only really like it if it's oily and I don't need that!
