Yep.

#!/usr/bin/env ruby

require 'rubygems'
require 'chef'
require 'chef/client'
require 'chef/run_context'

Chef::Config[:solo] = true
Chef::Config[:log_level] = :info
Chef::Log.level(:info)
client = Chef::Client.new
client.run_ohai
client.build_node

run_context = Chef::RunContext.new(client.node,
Chef::CookbookCollection.new(Chef::CookbookLoader.new))

# Use resources directly
Chef::Resource::Execute.new("echo foo", run_context).run_action(:run)

# Build a recipe programatically, and execute it
recipe = Chef::Recipe.new("adhoc", "default", run_context)
recipe.instance_eval <<-EOH
execute "echo bar"
EOH
Chef::Runner.new(run_context).converge

Best,
Adam
