Birthday food?

We are doing a farm theme birthday for our son. We got half chocolate, half vanilla cupcakes with white frosting and a matching white vanilla smash cake. They all have fun rainbow sprinkles on them for the desert. What I’m stumped on is the actual food portion, we are gonna be doing his party around lunch time,preferably after his nap, so he should be pretty hungry. My husband suggested just doing pizza, which is simple enough but y’all I’m so tired of eating pizza 😩😂, so my next thought was doing a taco/nacho bar. However I didn’t know if that would be weird to do with a farm theme party? I also thought of doing like a bbq bar, but that might be way to expensive and I’m trying to stay in a budget since there’s gonna be roughly 20 people there. I don’t know, what are y’all doing for food? Got any suggestions for me? This is some of the party decor 👇🏼 don’t mind my messy house in the background 😂🙈
