tomato free Ratatouille

[olrob]

My wife is on a renal diet and can't have tomatoes. I would like to make a crock pot Ratatouille with veggies like zucchini, yellow squash, various colored (green, red, yellow, etc.) sweet peppers, onions, olives and eggplant.

I have checked out dozens of Ratatouille recipes and they all use tomatoes in various forms. How does it taste without tomatoes? Is there a substitute?

They all use eggplant with some recipes doing the old procedure of salting slices, wait 1 hour, press out moisture, rinse with water and pat dry.
One cook said that was unnecessary because modern eggplants are less bitter than those or years ago. Is this correct?

Thanks

It's a vegetable casserole, put whatever you want in it. It will taste great, just different.

I have cooked eggplant without salting it and pressing out moisture...

Chopped apples might make an interesting addition to the "Ratatouille without Tomatoes."
I've done meals for my friend's son who is on a renal diet and found these recipes to be very helpful: http://www.kidney.org/atoz/pdf/dialysis_cookbook.pdf
