1) Next time you go to that favorite restaurant, order that dish. Afterwards compliment & chat up the wait person, calmly telling them your lil gag issue w/ home veggies. Ask for the recipe nicely/pleadingly (in advance, practice Puss n Boots eyes @ home in front of a mirror). Speak to the owner or chef if need be. Be super complimentary (no ass kissin' its the truth). Tell them you will continue being a patron of their fine establishment even of you make it @ home too
2) Skip meals (I.F.) & purposefully eat veggies when your hunger tells you to find something, anything & that you MUST eat again. Eat some veggies, not too much to gag you. Do some actual fasting (I.F before attempting longer ones) & break the fast w/ a small portion of buttered, salted creamed veggie of your choice + a protein.
Over time, you can train yourself...
