Hi svnh.bell, you're in a lucky spot! It's great when management makes development a priority.
I would start by getting signed up for some certification classes relevant to your desired career path. Since we're on IFSQN, you might be interested in HACCP, Better Processing Controls School, SQF certs, etc. Maybe your company would be willing to send you to these courses if the team could benefit?
For me, 1:1s are a great time to pitch projects to management. I do mine with the CEO, so although he doesn't have a lot of food safety/technical knowledge, he can prioritize spending and shift the budget as needed. Thankfully, he trusts my guidance on what quality issues need to be addressed! If you do your 1:1s with someone who shares your field, you'll be able to get their input on your project ideas as well.
As for development, it circles back to projects for me. I learn the best when I actually do something or need to tackle a real issue. I can't just read about something and feel like I know everything about it. So if you're looking to develop your skills, think about how the business could be improved from the perspective of your skillset. How could things go faster, safer, or more consistently? It all starts by identifying a problem, perhaps a bottleneck in the current production or testing process. Let your manager know you think you've identified an area for improvement in the process and that you're brainstorming solutions to propose. You'll find you can learn a lot by attempting to solve these problems.
