Jans,
You need to become an expert at two things - making blended fruit/healthy fat smoothies, and making veggie stir fry.
Buy frozen fruit. Buy frozen veggies. You can get these at your local supermarket in bulk quanities at discount price.
The problem with fruits and veggies are costs and the fact that they go bad. I have solved this for you, as in when you buy in bulk its cheaper, and when you buy frozen it lasts forever.
For veggies its simple - ALWAYS use organic butter(regular butter is made with harsh cancerous chemicals) and olive oil. Throw in butter/olive oil, get a nice sautee going, dump in veggies and whatever else you want, sometimes I throw in cheeses, nutts, various meats, fish and chicken, etc. I like to use a variety of spices. I really like steak seasoning on my veggies.
I drink one of my patented fruit smoothies everyday for breakfast and have veggie/meat stir fry every day at dinner. This way, and with lunch and other snacks in between, I get at least 10 servings of fruit/veggies per day, usually more.
Always mix it up. Sometimes I will buy a bag of blueberries and strawberries. Other times Im on a raspberry or blackberry kick. For veggies broccoli and spinich is a staple, but I like to buy mixes of it containing corn/potato/carrot/pea, there are so many to choose from. I eat like this every day, and it is totally worth it. I have pizza and junk food like everyone else, but its in small portions and maybe 1 - 2 times a week.
I like oranges,apples, beef jerkey and nutts as snacks, as they are portable and don't take any prep. I carry them around with me everywhere, take to work, always available.
