I agree with squidipa, bolognese is great to keep in the freezer. That way all I need to do is cook pasta. Even DH can manage it.

One thing I always had in the freezer was pizza. I would make really nice ones myself and wrap in glad wrap. They don't take long to cook, even straight from the freezer. They were tastier, cheaper and healthier than take away pizzas.

Another thing I always have in the freezer is fish, chips and those steamer bags of veggies. It isn't a gourmet meal, but again it is better than take away or toast.

I also found that evenings got a bit hectic. Lots of bubs seem to need more attention at that time of day. I would make the most of the calmer mornings. Cut up veggies and prepare things in advance.

I used my slow cooker a lot as I could put it on in the morning and it would be ready at the end of the day. Lots of people don't use these in summer, but they are a good option because they don't get very hot and don't heat up the house.

I would also try not to cook things that required my attention at the stove. Meals that can just be popped in the oven or microwave are less stressful. Again, frozen fish and chips are good for that.

Another easy meal is a quiche and ready made salad from the supermarket.

I hope some of this has been helpful. Now I need to get to the shops to get food for my family!
