From my experience (looks like it will work for any bent, I did this for T50 and the first part for Challenge Hurricane that I tested):
1. Search for a quiet slope, better if its a U shape, where you can go downhill then uphill. Also make sure it's free/almost free from cars. The U shape is good as you can get to top of the hill without having to push your bike up too much.
2. Just go downhill without any pedalling with feet dangling to prepare for any fall. At this phase learn to balance and brake. Repeat untill you get the balance and breaking right.
a. Go slowly first, Straighten the handlebars and always ready on the brake
3. Next is going downhill with feet on the pedals. Alternate your feet position : left foot forward, right foot forward, left foot up, right foot up.
4. This time start the pedaling. Go with the lowest gear, and start pedalling slowly while going downhill. Increase your cadence and gear when you feel comfortable with the current cadence and gear.
a. If its a U-shape, you can also feel how its like pedaling on the climb, and then stop once it gets too hard, dismount and push the bike to the top
5. Now, try to start moving on a flat surface like playing ground/empty parking lot. It may need a push or movement first.
6. Do straight lines
7. Do turns
8. Do circles, start from a big circle and make it smaller and smaller. Do right turning circles and left turning circles
9. Do the 8 shape / Infinity shape. start from a big circle and make it smaller and smaller. By this step, you just need more miles on the bike to gain confidence and competence.

Issues:
1. Left and right balance. Many people are righties, including me, so Recumbents, which require left and right to balance are a bit hard. You will tilt to your left side many-many times as you learn. Your left side will be hurt as your muscles learn to be active
2, Pull technique to balance. Pedal left, pull the left handlebar ; Pedal right, pull right
3. Push technique to balance. Pedal left, push right handlebar ; pedal right, push left
4. the push technique, although harder, comes handy if you are pushing against the seat to have more power to defeat a climb
