There are lots of quick meals you can prepare in 15min or 30 min; the trick is planning and shopping in advance, the weekend before; however even 15 min can be long if your children are starving.
Could you feed them a more substantial snack (Sandwich, Wrap, fruit, yogurt, nuggets, veggies) so they can wait a bit longer for dinner. Perhaps, you can cut down on after school club. DD1 did a lot during year 4 I ended exhausted, we have cut down to a more manageable number of clubs and have now more time to spend as a family cooking and doing other things.
Jamie 15 min meals is great.
A few ideas:
Smoked Salmon Risotto : www.bbcgoodfood.com/recipes/5965/smoked-salmon-and-lemon-risotto
Homemade hamburger: Hamburger meat already shaped, cheese, lettuce, bacon, tomato, cucumber.
Meatballs and penne pasta. Meatballs already shaped, fry in a pan, add, plum tomatoes, basil, mozzarella. Boil pasta and put on top of meatballs
Ciabatta roll with sausages: I buy sundried tomatoes sausages from the butcher, but any nice sausages will do. Cheese, tomato, lettuce, cucumber
Jamie's Smoked Fish Fettuccine
Cottage pie: cooked on the weekend and used leftovers for weekdays
Pasta Bolognaise: perhaps cooked during the weekend and leftovers for the week
Leftovers from Sunday roast and used meat for sandwiches, or chilli con carne or beef rendang
Chicken curry legs with rice and salad. Put chicken legs in the oven, cut and onion and put in the pan, add curry powder and chicken
Salmon, grill or in the oven with veggies and potatoes, boiled or mashed
Spaghetti hoops, fish fingers or chicken nuggets, veggies
Wraps with chicken, steak or minced lamb with spices, hallumi cheese, salad, Greek yogurt with lemon and mint, you can put cucumber, tomatoes, anything you want
Steak with frozen potato wedges in the oven and salad.
Chicken: cut it in small pieces and grill it, sweet potato fries cooked in the oven and veggies.
Leftover chicken salad, lettuce, tomatoes, cucumber, parmesan cheese
Perhaps you can cook the night before when they gone to bed and have the meals ready when they come home. James’s 15min meals has some good recipes
We cooked about 4 main meals a week and used left over or frozen things the other days or sandwiches, readymade soups, garlic bread.
