I followed your example and changed the port name in foo-api-v1 service from http to grpc after reading https://github.com/istio/istio/issues/46976#issuecomment-1828176048. That made this

export INGRESS_HOST=$(kubectl get gateways.gateway.networking.k8s.io foo-gateway -ojsonpath='{.status.addresses[*].value}')
grpcurl -authority grpc.example.com -proto helloworld.proto -format text -d 'name: "Jimbo"' -plaintext $INGRESS_HOST:80 helloworld.Greeter/SayHello

work for me with this gateway:

kubectl apply -f - <<EOF
apiVersion: gateway.networking.k8s.io/v1beta1
kind: Gateway
metadata:
  name: foo-gateway
spec:
  gatewayClassName: istio
  listeners:
  - name: demo
    hostname: "*.example.com"
    port: 80
    protocol: HTTP
    allowedRoutes:
      namespaces:
        from: All
EOF
