I personally love roast veggies. The issue with eg stir fried or sautéed vegetables, for me at least, is that they don’t microwave well because for both stir fry and sautéed veggies, part of the appeal is some crunch that remains in veggies like broccoli, carrots, baby sweetcorn, etc. But microwaving them to reheat just makes them go mushy. With roast veggies, they are quite soft anyway, so as long as you are not going for a crispy exterior they will microwave well.
I guess that’s one of my big issues with vegetables, is that I feel I usually have to cook them fresh. Otherwise the texture is not nice to me if I cook a lot of veggies to reheat over the next few days.
For roast veggies: olive oil and whole cloves of garlic with the skin on. You can smash them to release more flavour, but that also makes it more likely that the garlic will burn, which is a shame because roast garlic makes for a delicious garlic-flavoured spread on toast. Add whatever seasoning you like; I go with rosemary and then whatever spices on my spice rack look good.
I think people who didn’t grow up eating tofu, or just haven’t eaten a lot of tofu, may easily believe that tofu has no flavour. Or maybe if your nose/tongue is just less sensitive. I can most easily smell it when tofu is frying in a pan, personally. Like I said, it’s really subtle, and easily overpowered.
