The first meal I taught my kids to make was baked ziti. Not only is it only a few ingredients, but it's basically one pot prep aka fewer dishes to wash.
Baked Ziti
1 lb Ziti
1 qt spaghetti sauce
15 oz Ricotta cheese
1 c Mozzarella, shredded
1 Tbl Parmesan
Cook Ziti according to package directions; drain. Pour 2/3 c sauce on bottom of 13x9 pan. Combine Ziti, Mozzarella & Ricotta with remaining sauce. Spoon into pan & top with Parmesan. Cover & bake at 400 for 40 minutes, until hot & bubbly.

DD was less excited about making this one, because she hates to touch raw meat.

I made her toughen up & use a fork to pick up the meat.

She loves it & says it's not as bad as she thought to actually make.
CHICKEN & GREEN “LEENIE”**
1 lb boneless chicken
2 Tbl butter
¼ c Lea & Perrins Worcestershire for Chicken**
Melt butter in pan & add Worcestershire & chicken in single layer. Cook until edges turn white, then turn over. Sauce can be served “as is” or thickened with cornstarch or Wondra.
[NOTE: Works extremely well for fish filets as well.]
**The name of this has changed on the packaging, but we still call it that. It's now officially called "Marinade for Chicken: Blended with White Wine & Herbs".

This has more ingredients, but again is "one pot" & super simple since everything is pretty much "open & dump".

I usually brown several pounds of meat all at once & freeze in meal-sized packages. It takes even less time that way. I also cook boneless chicken in the crockpot and then shred it & freeze the same way. Chicken in the chili is really good too.
Chili
1 lb ground meat (or shredded chicken)
1 can tomato soup + can of water
1 can refried beans
1 can Great Northern beans (or kidney beans)
½ bag corn (frozen, defrosted)
1 pkg taco seasoning
1 Tbl chili powder
Brown the meat. Add remaining ingredients & simmer. Optional: Add a bag of Lipton Rice & Sauce - Spanish flavor with the amount of water listed on package. Serve with shredded cheese, sour cream, guacamole & tortilla chips, if desired.
