Meal prepping and eating a "balanced diet" on a budget.

I've been meal prepping my meals for the longest time now, I've always found it really helps me with weight and gives me a balanced diet.<br><br>But I just started my new job as a nurse and suddenly it feels like voila.<br><br>My salads, just some chicken and veggies and grains, cost me about £8 to make a day's worth. Which isn't too bad, and works out way cheaper than what I'd otherwise spend at Starbucks before work, but I still feel £8 is a lot.<br><br>Does anyone have any tips on how to make it cheaper?<br><br>Loool sorry I'm still new to this, and I'm probably in the wrong place x<br><br>TIA
