I too think your therapist could have chosen her words more carefully. (I also want to point out that if she's a therapist rather than a nutritionist, nurse practitioner, etc, while I would hope she would have training specifically to support body image, eating disorders and other related topics, it may just not be her specialty. She might not have the right vocabulary to be as helpful as another might.)
I feel like it makes sense that post-op, the focus is definitely on Eating For Nutrition rather than enjoyment. Obviously we want things to taste good, but that especially in the beginning when taste buds and hormones are readjusting, sometimes we need to focus on eating to recover and survive and heal, or what we can manage to get down if we're having a phase of lack of appetite, etc. As we heal and as we move through different stages of our diet, we'll naturally move towards making our meals more delicious while maintaining the healthy benefits we need.
Is it possible that your therapist misinterpreted your comments about missing food? Maybe you said you miss food, but were particularly missing solid and textured foods and things with a variety of flavour and they heard it as "I miss being able to eat half a pie or an entire pizza for dinner because it comforted me emotionally". Either way, I would've liked for them to say "Hey, it's temporary, food gets better" and "have you tried putting a bit of splenda and unsweetened cocoa powder on your yogurt, or put some fresh herbs in your broth and strain them out after simmering for 30 min".
