When I make mine I just throw what's ever in the fridge or the garden! In these ones I used shredded carrots, onion, garlic, and green peppers. Plus we had vegan sausage too :)
It's good to get your kids to try new things!! They might shock you how they're little taste buds change!! You can see from my daughters pix by the time I took her pic almost all her food was gone!!! Have a wonderful weekend!
