I made my kids sign up for SparkTeen and create 5 groups for each meal (5 breakfasts, 5 lunches, 5 dinners) to create shopping lists. The meal groups had to be reasonably well balanced and include some food compromises so that we don't have to prepare separate meals for everybody in the family.
I'm tempted to give each a grocery store gift card to help them learn to budget food expenses as well as nutrition. They'd have to shop from their SparkTeen food list and pay for it with the gift card.
I'm sorry their dad doesn't support your efforts in this regard, but the kids will be inspired by your positive results.
