My tween is my best eater. He likes just about everything I make. My current rotation is:
Enchiladas made with beans, corn, potatoes, chopped greens in an oil free sauce I found at sprouts market. Diaya cheese sprinkled on top if I have it. These were alot easier to make than I thought they'd be.
Pot pie made with peas, corn, potatoes, carrots, chopped greens, mushrooms in veg. broth and baked in a pilsbury pie crust. Please don't knock the pilsbury, I don't even want to know what's in it. These little crusts make life so easy and what's inside makes up for the little bit of crap on the outside.
Standby pasta and sauce. Try the prego light smart sauce. It has no oil in it! I saute onions and mushrooms first, dump in the sauce and pour over pasta. We usually have a wheat french bread with this.
We've tried the walden farms white sauce and have gotten mixed reactions. I don't eat it but from a taste it is somewhat sweet and thinner than traditional alfredo sauce. The 11yr. old loves it though. I put this over pasta with mushrooms, onions and mix veg. on hand.
We make vegan pizza with a crust I found at sprouts. It doesn't have diary in it. The oil free sauce and diaya cheese that's it. Sometimes I put pineapple on it but not usually. I have to make alot of these because they're popular and not very filling. The family gets more oil in their diet because they aren't overweight. I stay away from the pizza unless my weight is under goal.
Stirfrys are always a hit. I go back and forth between putting it over rice or over noodles. The 5yr old wouldn't eat rice for the longest time.
tacos (tostadas, burritos, mex. food is all the same, just different wrappers)- refried beans no oil, shredded carrots, corn, iceberg lettuce, olives, salsa, whatever else. These are fun. I make them ahead though and put a bunch of premade tacos out on the table. Again with the shells, a little crap for a whole lot of veg. I'm sure they have palm oil in them (ugh!)
I know this is going to sound cruel but I try to make one meal a week that the kids aren't crazy about. Right now it's the mixed veg. beans, chopped greens diced tomatoes over pasta. They don't love it but I do because it's easy. Pretty soon they'll get used to it and I'll have another cheap easy meal to make. I think we overall spoil our kids and they should get used to eating things even if they don't fall in love with it at the first bite. I try to have a dessert after this meal for extra encouragement
Also, get used to buying chopped greens if you don't already. Mix a little into everything you cook. You can't even taste it.
